Get a samsung spinpoint 1tb. Unless you have 2tbs of pictures worth of yourself, there is no reason for getting 3tb even WITH a $25 off. Harddrive prices are always going down. By the time you max your 1tb, prices would have gotten down by a bit.
Check it. If you lack the intelligence to see that then that is your noobish issue. Also, I really don't get the logic in your reasoning IF the i5-2500k bottlenecks a 560ti then why would you suggest a WEAKER CPU i5-2400 with a STRONGER GPU GTX570. I know bottleneck sounds cool for you but you shouldn't just throw it and throw that without checking the facts.
