I have a 7770 right now as my main GPU. I was initially thinking a crossfire setup. Im now rethinking the situation because of them being a pain sometimes.(Said multiple times by Logan and others) I want to get an upgrade, but Im not sure what I should do. Should i go crossfire because its cheap? If not i was thinking MSI 7870 hawk edition or MSI 660 ti power Edition. Or should i wait for the new AMD cards? Im really on the fence here and would love to hear what you guys have to say.
Hands down get the GTX660 ti, It trades blows with the HD7950 in most games and has less frame latency. I was also wondering before christmas which to buy and done some "research" and all in all the 660ti is the better purchase. With latest drivers the gtx660ti has gotten a nice little speed bump aswell (albeit so has the hd7xxx series).
*Just a note - The few circumstances I would recommend the AMD cards over the Nvidia would be when you are playing at Extremely High resolutions (2k +) or you maybe want to run dual monitors with eyefinity, the Nvidia cards (anything under gtx670 - aka 660ti - 660 - 650ti) have a memory bandwidth deficiency when it comes to the upper range of resolutions. Also to add in favor of AMD would be that it has the advantage of MSAA on its side.
Id say 660 ti if they are the only options, but you can get a 7950 for the same money as a 660 ti.....and a 7950 will spank the 660 even before you take advantage of its huge over-clocking potential. And as Phosgene said, new cards dropping soon, so expect even more price drops on the 7950's
Im running a 7950 (which i bought over the 660TI) and Oc'd with the 12.11 Drivers im getting frame rates/scores that a GTX670 is around maybe even a little less than, and as for the frame Latency, AMD has already stated theyre releasing new drivers to fix the issue and that it was caused by the majour Architecture change going to GCN
2 7770 will match a 660ti and almost match the 7950... and beat most 7870 cards (though the tahiti core XT/LE/MYST cards would likely match or beat it... it would be close)
So the cheapest boost in performance will be to xfire your 7770... of course that comes with all the headaches of xfire... here is a quick question... does your current 7770 have 2gb of ram or 1... cause really if you want the most out of the xfire setup, you'll need 2gb versions of the 7770.
