October is the last date I saw for it. You won't go wrong with an i5 if you need to upgrade and have the cash, they're brilliant frankly.
If you've a good quality 700w PSU then power isn't an issue, you'll not be getting close to the full limit of it.
Mmm, CPU may just not be stable at those speeds then, it happens I suppose.
Well, unfortunately money is a little tight. Which is why I've been looking at CPU's I could swap out without buying a new motherboard, (an AM3 board.) I've been looking at PC Mark benchmarks, and looking for AMD chips with roughly comparable scores to i5's and i7's. The Intel chips are definitely better, but I figure that so long as I'm in the same general neighborhood, the CPU shouldn't be a significant bottleneck.
Cheapest i5 comparable chip I've found so far is the AMD FX-6300 Six-Core, which costs roughly 100USD. I was asking about it earlier, but figured I'd be better off waiting a little while and buying the chip that scored closer to an i7 than an i5.
