Picking out components for your new gaming PC can be a tricky business – when it’s time to select the components required to construct your partner in battle there are numerous factors to consider, from compatibility issues to performance bottlenecks, all must be overcome in the journey to find that perfect mix of kit that will deliver the knock out performance you crave. Well today is your lucky day, as we’ve put together four different PC gaming systems, to suit four different budgets, ensuring that each component works flawlessly in unison with the others, and we’ve have four of the UK’s leading online specialist resellers in our corner to help you locate the best prices, so dig on in and pick out your new gaming PC rig – all you have to do is assemble it!

Unlike our first-time-out entry level machine from Ebuyer, this PC gaming rig from Dabs can comfortably handle the latest PC games at 1920x1080 and offers plenty of options for upgrading in the future. If you are looking for a powerful machine to mash the competition and keep you in the gaming ring then look no further. To power the graphics subsystem we've picked one of the best mid-range GPUs on the market, the Asus NVIDIA GeForce GTX 560 810MHz graphics card, a slightly modified, overclocked version of NVIDIA's recently-released GeForce GTX 560 and like the GTX 460 before it, this GPU is all about performance Vs. £££s.

The CPU has been upgraded to a second-generation, mid-range 3.1GHz Intel Core i5-2400 Sandy Bridge processor. With the aid of our trusty ring man, the mighty Artic Cooling Freezer Pro heat sink and fan – coming in at only £14.99 you cannot afford to not buy it. The i5-2400 will happily reach an overclock of 3.8GHz, but if you want to go higher you'll need to splash out another £20 for the Intel Core i5-2500K. Free from the shackles of Intel's overclocking cap, the 2500K can reach speeds of up to 5.7GHz, though a more realistic air-cooled target would be 4.5GHz.

Through our research we discovered that Dabs had stock of all components required for this build, not only are they one of the first to market with new products but their levels of availability are nothing short of excellent.

Our chosen motherboard is the Gigabyte Z68MX-UD2H-B3, is one of the most reliable Sandy Bridge motherboards in its price bracket and uses the latest release of this awesome chipset. Built with all the top-end components you'd expect from Gigabyte, the UD2 also sports several USB 3.0 ports, ensuring that any USB 2.0 devices work as quickly as possible, and allowing you to make full use of high-speed USB 3.0 devices as they become commonplace.

The UD2 also supports 2-Way SLI, allowing you to double the power of your PC's graphics subsystem by adding a second GeForce GTX 560 graphics card at a later date.

The more powerful components necessitate a more powerful PSU, so we've chosen the rock-solid Corsair 750 Watt TX EnthusiastSeries, which also supports NVIDIA SLI, should you wish to perform the aforementioned upgrade at a later date. Our chosen RAM is also very special and comes from Corsair again, the Vengeance memory is an 8GB kit (2x 4GB modules) so is double the capacity of the memory in our first system and with 1600MHz chips really keep things moving. The brand of the hard drive remains unchanged but the cache has doubled from 32MB to 64MB, this will help get data on and off of the drive faster.

The case and the rest of the components mirror the excellent selection found in our entry level system so will perform fantastically at this level and deliver jaw shattering performance.

Our pièce de résistance is the Mama Says Knock You Out of rigs, designed to do everything at once, without question or compromise. Thanks to the raw power and multiple video outputs of the GeForce GTX 590 graphics card, our Extreme PC gaming system can happily play the latest tessellated, PhysX hardware accelerated, DirectX 11 PC games on three 1080p monitors, simultaneously and all in glorious NVIDIA 3D Vision. Our CPU and cooling system remains unchanged, as does our Gigabyte UD7 motherboard simply because they really are the best you can get, whilst there are more advanced Sandy Bridge motherboards out there, our UD7 is simple and uncluttered, with 24 Phase power circuitry and ultra-reliable dual BIOS technology you need look no further.

We opted to buy the components from Scan Computers for this build as they are not only killer on price, boast one of the widest selections of components in the UK but they are also unrivalled when it comes to customer service tech support. When you are building a rig this complex you need to have someone in your corner should you get stuck – for us that has to be Scan.

To support the GTX 590 and our other kit, the power supply has been bumped to a 1200 Watt Corsair Pro Series 1200W Modular SLI Ready PSU, though if you intend to create a Quad SLI system with a second GTX 590, go for a 1500 Watt PSU instead, such as the Silverstone ST1500.

As this is an Extreme gaming PC build we've gone wild and gifted the system with 16GB of RAM. Sure, 8GB would suffice, but if you're building a computer this powerful you're surely going to be running three MMO clients simultaneously, whilst also encoding home movies and editing in Photoshop. In all seriousness, there is logic behind this decision – the 'sweet spot' for the amount of RAM increases every few years, and as this system will last a very long time indeed, we're sure that figure will rise before our build becomes obsolete. The chosen Corsair Vengeance kits are designed for maximum heat dissipation so that optimal performance is maintained at all times, especially when the power is cranked up.

Our hard drive config is now set up for ultra-high-performance, two 10,000rpm Western Digital Raptors in RAID 0 have been selected for killer storage performance. We could not stop there, sure you will struggle to find a faster option for large data storage but it is just not enough for us. No, we decided that the primary system drive should be a solid state disk or SSD, so we have used an OZC Vertex 3 240GB drive, with its 550MBs/sec read speed and 500MB/sec write speed the system will boot in second and ensure games load in a flash (excuse the pun). We'd recommend storing only the most demanding games and the operating system on the SSD, using the Western Digital Raptor drives for everything else, with one partition of RAID array for other system files and games, and the second for everything else.

Finally, we come to the case - for the Extreme system we've chosen the Corsair Obsidian 800, one of the best Full Tower cases on the market, giving you plenty of room for multiple video cards, additional hot plug hard drives and in our opinion the best cable routing in any case today – It is what my PC at home is built into and for good reason, it rocks.

So there you have it, if you want a gaming PC system to conquer the world, destroy your enemy and dominate your opponent with crushing performance this is the system for you. No matter what your budget all of our systems in this selection represent the best technology available today, at the best prices from the best resellers in the UK.

Now all you have to do is buy it and build it.

Game On, The NVIDIA Team!!
