Re: Are these parts compatable?
Alrite, you look like you have the start of a good build. Nice mobo, has room for expansion with the pci x16 slot, and supports ddr2. Good processor, should handle just about every application out there with ease. Might want to invest in dual core since more programs in the future are going to utilize that. I'm kind of iffy on your video card. I say spend some more cash, and get the 6600gt. It has a higher memory, and core clock. However that card has 256bit gddr3, while the 6600gt only supports 128bit ggdr3. You may be able to get more features out if you overclock it or use a program like Rivatuner, but I'd just go with the 6600gt. Also, you might want to look at this ram instead of the one you already have. It may be pricey, but it has lower latency and is dual channeled, so you'll get more performance for your money. Good luck, and happy building!
