I am in a position where I am not entirely happy with my grphics performance at the moment and would like a little bit more oomph. However, I dont have a lot of funds to spare (totally skint actually but NEED more GFX). My potential options are as follows: Sell 4870 512MB on ebay (£70) + purchase: ASUS 5850 1GB EAH @ £220 or 2*HIS ATI Radeon HD 5770 1024MB (Crossfired) @ £230 Or the most cheap option is to persevere on Ebay and the other used PC parts sites waiting on someone who is actually willing to part with their 2nd hand 4870 512MB at a reasonable rate (imo this is £70 and not a penny more). So: Buy Used 4870 512MB and Crossfire with existing card. My view on DX11 for the time being is that alhtough it would be nice to have, I don't really see it as becoming all big a deal for the forseeable future with PC games developments being tied down by consoles. For example, DX11 Bad Company 2 does look nicer than DX10...but not by much at all. Also, my tower is just some Coolermaster thing that resembles a fridge (looks, not temps) which I picked up for £50 in local computer store before I really grew wise to the merits of top quality PC goods.
