I currently have a GForce 460 1gb card in my system. Im looking to upgrade and looking at two different setups. I bought a CF supported last year just so I could CF in the future it was not in the budget at the time. Dont ask why I bought a Gforce card. . . I dont know. What Im looking at is the 7770 in cf which runs 159.99 on newegg. The 6870 is 164.99. I guess my question is , How much faster will my pc perform with the 7770 CF over the 460 , and is the 6870 alot faster than the 7770. Im thinking since the 700 series is brand new im paying for the newness of it because the 6000 series equivalent is quite a bit less. Also Contemplating to save a bit of cash getting two 6670 but I dont know if it will be much better than my single 460.
AMD Phenom 955 clocked at 3.8 per core
12 gig of Gskill Ripjaw series
60 gig Crucial SSD
2 tb on three other HD's
Geforce 460 GTS
I would wait for the release of the 7800 series from AMD. There's a huge hole in between the 7900 series at $440+ and the 7700 series at $150+ that the 7800 series cards should fill and they should be in the price range of ~$300 for a single card. The 7000 series cards run cooler and are more efficient than the 6000 series for not much gain in performance.
By 2%. I linked this because it also includes CF results. Slots in "just under"/technically slower then the 6970. Hopefully that chart helps. (One thing I don't like about that chart is it includes all resolutions. You should pay attention only to the the res you play at and the few around it.)
