Basically, need decision between these two:
EVGA SuperClocked 01G-P3-1563-AR GeForce GTX 560 Ti (Fermi) 1GB 256-bit GDDR5
-and-
MSI N560GTX-TI Twin Frozr II/OC GeForce GTX 560 Ti (Fermi) 1GB 256-bit GDDR5

Thoughts: MSI card may be more compatible with MSI mobo and Afterburner, while EVGA works with Afterburner (from what I hear) and Lifetime warrenty supports OCing... (also cheaper).
Heard of some complaints on MSI GPU heating up Case (I'm using Antec 300 Illusion)
Thanks!
