I live near a Fry's electronics and am getting Windows 7 and a new 1TB or more hard drive for my PC. I do game. and if I have to I have 1 dual channel that supports DDR 2 ram and will buy that if need be.

Since currently I am running Windows XP 32bit and have 2gb of 32bit ram which Id like to not replace but will if you think I should. Should I get Windows 7 32bit or 64bit and if I get 64 bit should I get 64bit ram and like 4gb of it? and my final question is what are some solid names of ram and hard drive manufacturers

first off, good choice of finally moving on from XP :P ...well as far as 32bit vs 64 is concerned here is the answer:
Should You Install Windows 7 32-bit or 64-bit?

as far as a good hard drive manufacturer, i think many will agree that western digital is the way to go, their hard drives are well prices and available in all capacities and some are available with 5 year warranty ,an example would be the WD Caviar Black 1TB which is available with 5 years warranty and costs under a hundred dollars
