A few posts back I asked:
Ok I have a Intel first Gen Mac Pro, it has 2 X 2Ghz Dual Core Intel Xeon,7GB 667 Mhz DD2 FB-DIM ram,NVIDIA GeForce 8800 GT 512 MB, Resolution: 1680 x 1050, I did have the 30inch but figured I would go with the smaller monitor I have everything on low or None, but all I get is 5 FPS and or 2 to 5 in Lion's Arch and DR as well. I have 10.6.8 SNow Lep, will getting 10.8.x help at all?
I "" someone but got no answer I was told today I can only goto 10.7 the most I can go I also, was told I can get the ATI 5570 I believe witch is backwards compatible with this system I want to know since I don't have 250 dollars right now for the card would getting Lion make a difference since I'm getting 5fps here and there?
