Hi guys, need balanced opinions here 
Currently running the following:
C2D E6750 @ 3.2ghz
2GB
2x 250GB HD
19" Asus monitor (max res 1440x900ish)
Nvidia 8800GT with Thermalright HR-03-GT VGA Cooler
Vista 32bit
Currently playing the following:
GRID / Crysis / Warhead / WiConflict / Bioshock / TF2 / Stalker / Trackmania
Im getting back into PC gaming after a long hiatus (had no time for it), and i've been building a PC for a mate, who lacks a graphics card. I've told him ill flog my 512mb 8800GT (with Thermalright HR-03-GT VGA Cooler) for £50, which means I can probably pick up a 4850 for £50/60 myself.
Question is, hows the day to day difference in 1) Those games listed above? 2) Future games? I'd like the card to last at least a year or so...
