So recently I purchased a Sapphire Vapor-X and it's been working great so far, but today when playing both Team Fortress 2 and GTA IV I suffered severe lag. On Team Fortress 2 I was just running around with hardly anybody on the screen when my FPS kept jumping from 60-10FPS and this lasted for around 30 seconds, I had the exact same issue with GTA IV when walking through a building. I haven't overclocked and I'm using the 10.4 drivers
System specs:
AMD Athlon 630 x4 @ 2.8GHz
Geil 2GB DDR2 RAM
Biostar GF8100 Motherboard
Seagate 250GB HDD
Corsair VX550
Also when this happens my temperatures seem fairly normal:
CPU 38 Celcius with the fan at 4000rpm
GPU 53 Celcius with the fan at 40%
