My current rig currently does everything i need it to, and with some hidden gems in the price to performance department.
My CPU & Cooler:
Intel i7-2600k & Cooler Master Hyper 212 Evo - 100gbp
The reason for this purchase as it was a i7 @ 3.4ghz with potential to overclock for 75gbp. This was a present however and is currently running around 4-4.5 (im still overclocking it and finding things which just kill it. The cpu cooler i use is almost the cheapest you can get whilst still being able to overclock with solid results, I do have plans to replace the fans on my cooler, but i need to decide upon certain factors which will decide the one i buy.
My GPU:
MSI TwinFrozrr GTX 760 - 65gbp
Its a gtx 760, I had originally intended to pickup a R9 270x but this was in stock and 5gbp cheaper. So that was what was purchased. CEX Purchase like my cpu. DOES NOT LIKE BEING OVERCLOCKED.
My Motherboard:
Gigabyte z77x-UD5H - 115gbp
This is easily the most expensive part of this build, I couldn't any z68/z77 boards anywhere (even ebay), and then suddenly one turned up at a local computer shop, brand new 1155 board in 2018.
My PSU:
CX430 - 35gbp
Works and keeps my PC powered, no issues and its lasted over 1 year.
My RAM:
Corsair Vengeance LP DDR3 8gb + 4gb standard stick - 42gbp
Bought the Corsair at the start of 2017 from a big box store, was cheap compared to now, i got it for 30gbp and the second stick was 12gbp. Its clocked to 1600mhz.
Case
Kolink Observatory - 63gbp
One of the first in the UK to ever get this case, it looks like a Corsair 570x Crystal. RGB fans come included however are remote controlled. Cable management brilliant, comes with fan hub and everything you need.
Keyboard + Mouse
Fnatic Flick + Drevo TKL Keyboard TYRFING - 60gbp
Mouse signed by KennyS + NBK and mousepad signed by many of the professional cs players. Decent keyboard (cherry mx reds) not rgb. Mouse is really nice, nice size, grip and glide.
Audio
Logitech G430 - 45gbp
Good base, they actually sound better in music, however still do perform quite well in games. Mics very MEH, sometimes drops and has lost tension.
