Welcome to OCC
The Build you've laid out looks Very Good
There will always be a 'but' or 'however' though
1. I've never recommend the 560Ti-448 to anyone for a single reason: Price. The GTX560Ti-448 are priced really close to the GTX570s but their performance aren't worth the -$30 price tag. If you look at reviews, the 560Ti 448 seems to be very close to the GTX570. This is however not true since you'll have to Overclock the 560Ti 448 greatly to even achieve the same or better performance then a stock
GTX570. It has no chance competing with an Overclocked GTX570 and I (and many others here) can tell you that the 570 is a hell of a card in terms of Overclocking.
In short, if you could afford the 570, don't bother looking at the 560Ti 448. Newegg has a sweet deals for them with some having a 20% discount until 4/11.
Also, Do you really need SLI? If you're not planning on doing Multi-monitor setup, I advice you to keep away from SLI. SLI could cause issues with games (not always but sometime) and you won't be getting 2x the performance with two cards but 2x the power draw. If you're planning on gaming on a single screen, I recommend getting a single GTX680 instead and save the extra money.
2. If you're using this rig exclusively for gaming, you wouldn't need 16GB of RAM. 8GB is plenty for a gaming rig and SB doesn't support Quad Channel so you'll only need a Dual Channel kit.
Go with these G.Skill RipjawsX 8GB
instead of the 16GB variant.
3. If you plan on sticking with SLI (which I wouldn't recommend unless you're doing multiple monitor setup), I suggest you change the PSU for a 850W unit. I tend to stick with Corsair or Seasonic products since I've never had any units by them fail. Something like the Corsair HX850
should fit in nicely (it's an 80+ Gold product btw. They just upgraded it)
4. Instead of the Antec 300, I suggest you look on something with some more serious airflow, especially if you insist on doing SLI. I recommend something like the CoolerMaster HAF 932 Advance
or NZXT Phantom
(Although the HAF 932 is cheaper when you consider that it has all fans fitted in whilst the Phantom only has 4 fans fitted in).
Here's what I'd recommend you to get (Newegg prices):i5 2500K

Total: ~$1565 ($1550 after MIR)
Hope this helps
