PSU is extreme overkill for a pair of GTX 560 Ti's. A good 750W unit like Corsair's AX750 would do, or the AX850 would be a safer choice for future video card upgrades. Take a look here
- a GTX 560 Ti SLI rig with an i7 965 @ 3.75 GHz (far more power hungry than that 95W CPU you chose) peaked at 449W from the wall.
As for the CPU, I assume you don't intend to overclock since you chose the i7 2600 and didn't choose an aftermarket CPU cooler. If you don't want to overclock that's fine, but keep in mind that the only benefit offered by the 2600/2600k over the 2500/2500k is hyperthreading, which doesn't help much in most programs and doesn't help at all in games. Some games even run better with hyperthreading disabled.
I wouldn't get an EVGA Z68 since reviews show that their BIOS is very premature and lacking compared to others like ASUS. I'd give this case
some serious consideration, since its airflow design is better than any typical one. Quite a few people here and on other forums have switched from HAF cases to ones with this airflow design and got nice temperature reductions.
I'm a bit confused by your SSD choice. You mention cache, but list a regular SSD rather than an SSD cache drive (since OCZ doesn't have an 80GB cache drive). In any case, I hope you chose an SSD boot drive since this outperforms those cache drive. I'd go with this
. Intel is the best for reliability and this new 520 series is one of the very fastest.
Now one important note - Ivy Bridge comes out in a month or so, therefore I wouldn't build this PC yet unless you currently don't own a gaming PC.
