Dont get the £140 7850, it only has 1GB Vram. make sure you get a good custom cooler if you want to overclock (which you should). If you can get one with a decent cooler for £130 secondhand then go for it.Is it worth getting a £167 custom cooler 7850 (Sapphire/MSI/Gigabyte) over a reference 7850 at £140, or even a 2nd hand 7850 at ~£130? Really can't decide
