I have the once-in-a-few years option of upgrading my rig. I'm mainly interested in maximized gaming. Budget, and such details are already figured, as is the HDD, case etc... OS will be Win 7 Home Premium x64.
The biggest reason for upgrading is that I use eyefinity (5040x1050). Often I must reduce certain settings in games (skyrim, bf3 etc).
So the real question is: do the full upgrade, or just put a 7970 into my current rig. In other words, is the performance gained worth the $900-1000ish vs just the 7970 in the old rig for $370-$410? What % additional performance would I get from pci 3.0 vs 2.0 ?
I've been reading a lot more since I posted this. I'm starting to come to the same conclusion. I'm used to needing an upgrade every year or two, this rigs going on nearly three. Maybe I'm just being a computer lemming, marching to my costly cliff of doom. Some good prices on newegg sales right now, are luring me that way.
Maybe saving, waiting for Haswell is a better idea.
My only concern now, is how much benefit does that 7970 on 3.0 gain on 5040x1050 over the current 2.0? Some things say 3.0 only becomes worth it with 3x sli/Crossfi, others say anything over standard resolution. It's murky man... murky.
