Hi, I am ready to build my new pc. I want it to be moderately priced maxing at about 1000-1100 USD. I am using the Core2Duo e6400 as my processor(LGA775). I want to go back to nvidia video cards again. What chipset should I use for the motherboard the nforce x16 sli or nforce 570. Right now these are in my pricerange while the nforce 590 lga775 is a little too expensive. I see the nforce x16 sli has dual x16 pci express and supports ddr2 800 while the 570 has 2 x8 pci express slots and only supports up to ddr2 667. Thanks
