Hey guys, I was wondering if I could get some help with my first build. I'm not a hardcore gamer, but I would like to play a few games on it. I plan on using it as a workstation for things like computational chemistry and molecular dynamics simulations. I have a tentative list of parts that I was thinking about in addition to a few questions. My budget is around $1350. Here are the parts I was thinking about.
Case: Corsair 650D
Motherboard: (Not sure yet, but I want a regular ATX board)
Processor: Intel i7-2600K
Cooler: Corsair H60
GPU: Either a Radeon 6870 or 6950
SSD: Either Intel 320 or Crucial m4
HDD: Western Digital Caviar Black 640 GB
RAM: 8GB Corsair XMS2
PSU: Corsair Professional Series 750W
My questions are:
1. Is it a bad/good idea to buy some parts from eBay if I find a decent deal?
2. With regards to the motherboard, I originally wanted one with the Z68 chipset, but a lot of the boards are pretty expensive. I was thinking about this one, since it is has multiple PCIe 2.0 slots in addition to some goodies:
4. If for some reason I decide to Crossfire the cards in the future, would 750W be enough juice?
5. For the SSD, should I go with the Intel 320 series or one of the SATA III Crucial disks? The former is overpriced and only SATA II, but it seems that Intel SSDs are more reliable than the other ones.
