Replaced my old AMD 64X2 3800 setup with:
PNY VCGGTX550TVXPB GeForce GTX 550 Ti (Fermi) 1GB
Intel Core i5-2400 Sandy Bridge 3.1GHz
CORSAIR Vengeance 4GB 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
So my question is how much performance increase would I get if I add a additional CORSAIR Vengeance 4GB 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)? So I can get a duel memory channel. I am thinking some but not much due to my main bottleneck now is the HDD only a 5400 RPM drive.
