EDIT: 7200 RPM SATA II, gotcha.
Western Digital Caviar Black, or a Samsung Spinpoint F3. If you go with a SATA III drive, then you'll be kind if investing in the future because you're gonna want it if you upgrade to a new CPU/motherboard/memory combo (which you will have to do if you upgrade to a modern CPU).
Anyway, I am assuming that even the 750 Ti would be bottlenecked. I had a GTX 470 when I upgraded from the E8400/EP45-UD3P combo (I had DDR2-1200 memory as well) to my sig rig, and I noticed a difference right away in my gaming performance, long before I overclocked the 2500K. So right then and there, I knew that my E8400 was bottlenecking the GTX 470. We're talking about the 750 Ti, which is probably a much better GPU than the 470, so the bottleneck would be even tighter.
Still, if you were to get a good mid-range video card now, then you'll have it for if/when you upgrade to either Sandy Bridge, Ivy Bridge, Haswell, or Broadwell, or ...etc. (or the AMD equivalents). So, I guess it can be seen as an investment for the future. Plus, you have the 550W SeaSonic G Series, so you're all set for any single video card: even the best of the best - just as long as you keep the high-end video cards at stock.
