Thank you very much! I was looking for support of a Core 2 Quad, this makes the upgrade much more worth it. I will check it out, and look at the Q8400 to buy. Thank you again.

there are other models of the insipron 530, this one is the regular 530, Not the 530s or anything.

I bought this desktop from a thrift store, a Del Inspiron 530 for $13 runs perfectly, it even came with a graphics card. I decided to slide in a wireless network card and an ATi Radeon HD 5570(originally an ATI Radeon HD 5450) I had laying around. It has a 3GB ddr2 (going to upgrade to 6GB), Dell 0RY007 LGA 775 motherboard P35/G33/G31 chipset, and a Intel Pentium E5200 @ 2.5GHz 45nm. So what I'm wondering is what's the best CPU I can slot in this thing so I can play games (tf2, CS-GO, Minecraft and other games like those). Sources tell me conflicting information and other motherboards allow different things I hear. From what I hear quad core is out the window (Open the door to let it back in if possible on this motherboard) I need something at least better than a Core 2 Duo E6600 (I would appreciate marginally better!) I hear the Core 2 Duo E6600 is good. Anyways thank you in advance for any replies ~Nathan
