I've been away from simming for a couple of years, but am getting back into it. Recently purchased a new computer and FSX, and I know I need to upgrade the graphics card for a decent experience. I assume I'll need to upgrade the power supply as well.Current setup is a HP m7020n. Specs: Core

Whilst I am unable to locate a direct comparison of a 7320 and a 8600, the following link shows a 7300 compared to a 7600 with FSX http://www23.tomshardware.com/graphics_200...2=719&chart=291 - the 7600 is nearly 3 times quicker. Since this 8600 is even better than the 7600, then the gap is even wider between the subject two cards.The other benefit that an 8600 will give is that it is DX10 compliant, and since you already have Vista, you are only the upcoming FSX DX10 patch away from the next upgrade to our favourite sim series. Whilst a $300+ 8800 would be even better, it's pretty hard to go past the much cheaper 8600 (as low as $120 for the XFX 8600GT and $150 for the EVGA 8600GTS at newegg).Gary

Thanks, Gary. The 8600 GTS OC card is quite a bit more expensive (I think it's $289). Realizing this is subjective, any thoughts on if the performance gain might be worth it?

I'd say for marginal improvement over a $150 GTS at nearly double the price - no. For even less than the $289 Best Buy price, you can buy an 8800 GTS 320MB card (ie. next GPU class up) for $250 at the Egg per the following link http://www.newegg.com/Product/Product.asp?...TC-pr1c3grabb3r - that would be worth it!Gary

Right on, Gary. I spent more time yesterday researching and educating myself, and that's exactly the same thought I had.Alex
