HiMy PC, originally purchased for FS9, runs FSX reasonably if I am very careful with the settings.I have noticed that Vista gives the following performance rating for my system:Processor 5.3, Memory 5.9, Graphics 4.1, Gaming Graphics 4.4 and Primary hard disk 5.7 giving my system a performance rating of 4.1It also gives FSX a game requirement rating of 3.0 and a recommended performance rating of 5.0. This appears to confirm my FSX experience, it runs but not without significant concessions, and that the video capability is the weakest link.My questions are:How relevant and/or realistic are these figures?Am I likely to see a significant gain if I upgraded my video card (a GeForce 7600GS) to a top end model? I am unlikely to be able to afford a major H/W upgrade in the near future and wonder if a good card now would keep me going and then transfer to a newer system at a later date.What video cards would you recommend?What system performance ratings does Vista give to those owning a system running FSX at or near full pelt?Please keep it as nontechnical as possible at this stage.Current systemProcessor: AMD Athlon 64 Dual Core 56600+ running at 2.8 GHz.RAM: 2 GB occupying the only two slots on the M/B.Graphics: GeForce 7600GS with 500 MB of memory, which is a slower product than the GeForce.7600GT.Present software: FSX, Flight1 GEX and UTX for Europe and USA, ATR 72-500, Aerosoft My TrafficX, Cheyenne and Katana.Eventually hope to run: FEX, Global X mesh, Austria Professional, Scotflight’s scenery for Scotland and a really good model of a Cessna Skyhawk or similar to complete my hanger.All comment welcomeBlue skiesFlapless
