HelloI have been running FSX on an old machine and want to upgrade to get better performance. Until recently I've looked at a brand-new i7/920 and expect that would run me around 1500$ CDN. A second alternative would be to run on a PC I bought two years ago, after some upgrading. Below is the current config for that PC: Mobo/CPU/GPU/Memory/SW At the bottom of this message are upgrade CPU options that I found on the ASUS website. Here are my questions: Which CPU's do you consider are good price/performance options (I expect opinions may vary quite a bit on this!) Is 8GB of memory overkill? Would 4GB be enough? (I expect I will have to discard the existing 2GB) Is this motherboard/CPU combination a good candidate to overclock? I read somewhere that if the Mobo has onboard graphics, overclocking is not possible. I believe this mobo does have onboard graphics. Is it true that I should not count on overclocking it? Can this configuration be adequately air-cooled in a micro-atx case? Any recommendations on sink-fan? I'm totally new at this! Thanks in advance for your opinions!

You can hardly have too much memory, be sure to use 64 bit OS (win 7 or XP), but you

That board isn't that great... I'd swap it out for a cheap Gigabyte P45 board like the UD3L. I'm running two of them, 4GHz on a Q9550, and 4GHz on an E8400. Quite the board for $89 after rebate (Micro Center). Add a cheap quad like the Q9550 ($169 @ Micro Center) and you'll be on your way to an excellent FSX machine.
