I read your hardware and wondered what settings you may have in your BIOS to fix my low single digit frame rate. (a lot worse than my Athlon 1.4Ghz)I have same board and processor 2 meg of ram and will probably get the card as yours only other difference is I am using a single SATA drive.IAn

">>Mike T"Mike,Here's my question: Current System is as follows:AMD2800XPNvidia 6600GT 1281Gig 2700 RAMXP HomeI am considering upgrading to a AMD 64 3500 and 2 new SLi Video Cards that are bridged.1) Since I really want an FX57 CPU, should I wait to upgrade to that system or will I see a tremendous improvment from the AMD 2800xp to the AMD 64 35002) Can anyone truly say that the new SLi/PCIE cards are a tremendous help in FS? 3) When bridging two SLi cards, does it really make a big difference?

It does work in the AA Mode and I am running at 16 for both AA and Anisio. I can say that even though I have a fairly high end machine, I to suffer from the same issues that most are complaining about with FSX.Although with this rig I can, around the seattle area maintain about 22 frames, and the lowest being 15, depending on the complexity (i.e. Seattle skyline etc). This is using autogen, 1000,1000 for the tweak on the tree and autogen buildings count, Very Dense-Very Dense for autogen settings in the sim, NO default.xml and using stock textures. I run at 1600x1200 also. So not bad really, but even with that I am not happy. LOL, my tweaking habit (or addiction) cannot be cured! Personally Mike I feel your pain and it is hard to wait I know but I would not upgrade yet. Let the dust settle on ACES patch and let the drivers mature for Vista. This flightsim stuff is stressfull LOL. If you have the money to burn, you will see an improvement but it needs to be your choice as to whether it is worth it. Hope this helpsBob
