Well, I'm just starting an upgrade process to my existing AMD APU system. I recently bought one XFX 7870 BE to replace the old 6670. I am planning to get the FX 8350 and the ASUS MB. My current spec:

CPU: AMD A8 3870K @ 3.5Ghz
MB: MSI G55MA
RAM: GSkill Sniper 2x4GB @ 1600Mhz
PSU: Seasonic SII 430W
GPU: XFX DD 7870 BE @ Stock
Cabinet: NZXT 210 Elite Source
Cooler: CM Hyper 212
Optical: LG BR Drive
Misc: NZXT Fan Controller & Card Reader

After the GPU replacement, though I have noticed significant performance boost on ultra settings on all the games I play but I have been getting pretty frequent game crashes to desktop after say 30 mins to 1 hr of continuous play. I do see the GPU temperature reaching high 60's even 70's in GPUZ. My question is, what is going wrong? I have a pretty airy cabinet with 2 intakes and 3 exhausts. Is the PSU too small to handle the system? Is the GPU at fault? I am clueless here. Please help.
