So I got my new dell. I got a base model system and planned to upgrade parts myself since it will be cheaper or I could add better things than Dell had for their build options, and I also wanted a base model so I could get it quicker. it's a i7 with windows 7 64 bit premium. I want to eventually build a nice gaming system. not bleeding-edge high tech, but good.
So, first off I added a 2nd hard drive. main drive for OS and apps, 2nd for stuff and games. I read it's good to add the windows page file / swap file to the 2nd drive, but I also read you need to keep a small swap file on the main drive still. anyone know if that's true? or should I put it all on the 2nd drive?
I have 3 gb of DDR3 ram, usually about 40% full when the system is just idle. planning to add more, possibly to 6 gb. I think the ram is the slower bottom barrel kind, would I be better off just adding 3 gb more of better, faster ram or will it always be as slow as the slowest kind in there? should I replace it and get 6 gb of all new fast ram?
I have built in sound. My speakers are just 2
pc speakers with a subwoofer, I won't be watching
HD movies since I have a home theater and won't need 5.1 surround sound for my
pc, but do I want to consider a sound blaster card instead of integrated? will there be any performance boost if I do? I doubt it could make my system sound any better than it already does, but if it will help the processor process stuff better I might consider it...
now for the video card. it's got a ati 4350. I downloaded the crysis demo and I got around 2fps in full
HD 
So I want a new video card. I don't want to spend a lot though, so I won't be getting any $500 mega cards. I also can't do SLI or crossfire so I can only really have 1 card. I almost bought an ati 4850 this weekend, but would that be a worthwhile boost? on ATI's site their newer cards are up in the 5000's now, so I don't wanna buy something old and out dated. I was considering nvidia but I heard their current GTX cards are pretty much discontinued now and they are gonna release a whole new set around February. Is this true? I think I can spend around $200 on my video card, maybe $250 max. Any recommendations?
