My current setup is a slim case with the following components AMD 5000+ processor @ 2.6ghz Nvidia 7300gs 256mb 64bit gpu Crucial Ballistix 2 x 2gb ram 250w psu This is all in a slim case, so I am limited to upgrades. I prefer a slim case to hide it away from everything for less clutter. My recent purchases are Nvidia 8600GT 512mb 128bit AMD Phenom 9550 Quad core 2.2ghz cpu I am limited to the video card so I cannot upgrade to an 8800 or above due to the slim case. Would you recommend me keeping quad core or returning it? I don't notice any hesitation with my current processor, but I got this processor for under 200 with a 60 dollar incentive. I am just getting into computer gaming and I want a rig that can handle most games. Thanks for any insight you can provide.
