Hello! Recently I asked your help to replace my Video card (8800GT) and I got suggested for the HD 4870, but I have the chance to sell my current setup to a friend and build a new system for myself. In my signature is my current setup, and here are my questions... I have two CPU's the Q6600 and the E7300, is the Quad Core much better than the E7300? I would like to keep my Q6600 for my new system and sell the one I have to my friend with the E7300, I'm just willing to know if the 45nm and the 3MB cache make the E7300 better than the Q6600 or not. I was thinkinh about the i7, but at the moment it's too expensive, so I rather keep my Q6600 (if it's better than the E7300) and buy something like this... http://www.newegg.com/Product/Product.aspx?Item=N82E16813131231&Tpk=ASUS P5N-T Deluxe I really like that motherboard, because it has what I need, eSata, SLI (for future upgrade) 6 SATA side ports, is it a good choice to replace the P5K-E I currently have?, I replace that Motherboard because it's Crossfire and I'm willing to get SLI mainly but if you have other suggestions please let me know. I'll be getting a GTX 260, but I don't know if I should go with the 216 cores or stick with the regular 192, what do you suggest, the price difference it's only about $20, I would like to keep it under $200 for video card also what power supply would you suggest to power up this card, I was thinking on this one... http://www.newegg.com/Product/Product.aspx?Item=N82E16817139005 It has a single 12v rail with 52Amp, I don't know if that's better than dual and triple rails or not, what do you suggest?
