This is my first time building a PC from scratch so I'm pretty unsure on everything. It will be used mainly for gaming, and I'm also hoping that it will last me for a while. I've already got a case, a 500w PSU, and a 9800GTX that I want to use, and I'm leaning more towards Intel than AMD as far as CPU's go. I was thinking of getting an E7400 with a Gigabyte EP45-UD3P, but I was confused on what kind of memory would be compatible with that mobo? Is there something better that I can get for about the same price? Also, what would be a good choice for a hard drive, or does it not matter horribly?
