You will notice the diffrence between the Q6600 And E4300.
Can you tell me the settings you are using on your current E4300.
OK.. so I probably won't be keeping the card forever but..
e4300 @ 3Ghz
q6600 @ 3Ghz
Would you bother changing for gaming purposes? (as I'm concerned the e4300 isn't enough given that I see very little utilisation of the 4870X2 in games like BFBC2. (Crysis = 100% utilisation though).
Note: I would try an q9450 or q9550 but really outside of my finances at the moment.
Just playing the single player on BFBC2, it feels like an improvement could be made. (1920*1200, most settings on high, except shadows on medium, no AA and 8x AF). Feels a bit 'jerky' to me at present. Just moving 'forward' every few steps it seemed to jerk on occasion like it's loading something up. Wierd.
