I own one of these machines with a Q6600 in it with Windows 7 and 8GB of RAM and it runs great! I upgraded to the core 2 6700 and it improved a little, not much. Still tends to stull when i load up on with 6 to 9 windows open. Which I guess is normal. Question, i thought 4 GB of RAM was the realistic limit running a 32 bit system? Does all that RAM make a difference? Thanks!!! Score 0 dee9dog November 21, 2011 5:30:05 PM CharlieWalkerTX said:Actually this Dell Optiplex 745 can support a Intel Core 2 Quad Q6600 or and Q6700.

I would suggest anyone with Windows 7 that intends to do serious gaming get at least 2x 4GBs. RAM is really cheap so there isn't a good reason not to fit more than 4 GBs in a Windows 7 computer. As for the other question, I wouldn't upgrade anything except maybe a video card in the DELL. Save your money for an entirely new core. Cores are best upgraded as one "piece" so a Motherboard, Processor, and RAM should all come at once. You can get a Phenom 2 x4 840, M4N68T-M LE V2, and 2x 2GB Crucial Ballistix core for well under $100 if you are thinking of just upgrading the whole core and you are on a budget.
