Here's the line up (hoping it, too, gets the job done for lower budget): Mobo: Intel DP55WB w/ LG1156, CPU: Intel Core i5 750 Video Card: GeForce GTX 260 RAM: Corsair XMS3 (bunch of letters here) 4 GB dual channel. I have an old Toshiba Satellite A105-S4064 laptop with a 90 GB Hard drive, which is yet filled to half capacity and will continue to see use. The coputer I'm looking to build is to support StartCraft 2 on at least high settings. I have found no data about system specs required to run it on ultra, so if you have some info on that, you see the line up, drop me some advice. But the major question is for the hard drive. What, if anything, do I need to know or look for when it comes to getting a reasonably-priced unit?
