I am considering getting a 22" LCD panel and a 4870 to use with my current setup (E2200 @3Ghz). Just wondering whether the 4870 will be overkill for my cpu and whether the 4850 will be more than good enough? I'm not a huge gamer but like the occasional bit of FPS, PES, Flight Sim, etc. The reasons I'm looking at the 4870 is for future proofing (non CF mobo) and exhausting heat out of the case. Any advice?
