I recently bought myself all of the components needed for my gaming pc, except for the graphics card.
The parts i have in my build are as follows :
Corsair c70 case
Corsair modular 600w power supply
Asus m5a97 evo r2.0 motherboard
amd fx 8320 processor
cooler master hyper evo 212 cpu cooler
8gb ddr3 corsair vengence 1866mhz ram
2 500gb hdds
All i need now is a graphics card, my budget is max £150. I intend to play games on high settings if possible at this price range on a 1920x1080 monitor. I will be playing games like: The witcher 2, far cry 3, skyrim, dishonored, bf4 etc.
amd is the manufacture.... the rest of them are board partners who add customized coolers and distribute and sell them. if you dont plan on overclocking, then it doesn't matter, get the one with the best customer support and warranty. in this case, msi, gigabyte, and sapphire are all well known trusted brand names. their all going to generally overclock the same so for that card series for me, i would get the one with the best rated cooler that is quiet and offers decent temps.
Agree on the R9 270, probably best of the current cards for the price but a few other words.
The HD7870 is, to all intents and purposes the same card and you might find one on offer with a little searching.
The much better GTX760 is not a huge amount more, I'd strongly suggest you hold off and go for one of those instead-it's a better long term option.
If you've not already done so, have a look here: Dabs, CCL, Ebuyer, Scan, Aria, Pixmania, Novatech, Overclockers and Quiet PC. And Amazon.
