So I've had this gaming pc up and running since Septermber 2008 and I'm considering upgrading it. One reason is that there seems to be a huge bottleneck somewhere in its performance. To summarize the problems: In World of Warcraft I've been getting framerates of less than 7 when standing around in Dalaran, on and off of peak gaming hours, while getting 40+ flying around the rest of the game. Also my frame rates drop dramatically during large boss encounters and massive particle and graphical effects. So it sounds like there's a graphics card incompatablity happening somewhere, but could it also be a motherboard/cpu incompatability? Here's the specs:
AMD Phenom 9600 Agena 2.3GHz 4 x 512KB L2 Cache 2MB L3 Cache Socket AM2+ 95W Quad-Core Processor
ASUS M2N-E AM2 NVIDIA nForce 570 Ultra MCP ATX AMD Motherboard
Rosewill RD550N-2DC-SL-SLV 550W 12V V2.2 / SSI standard EPS 12V Power Supply
NZXT Alpha Black Steel ATX Mid Tower Computer Case with Open Window
nVidia GeForce 9600 GT video card
4 gigs of DDR2 memory
Could an AM2+ CPU on an AM2 motherboard be the problem? Are there other compatability issues I'm not thinking of?
I've been considering upgrading my system anyway, and I was hoping for some feedback on where to start. If the motherboard is indeed the problem, and upgrading it critical, do I go to an AM2+ for the compatability or jump to AM3 and starting rebuilting from there?
Basically I want a powerful, reliable gaming machine, and if my current setup (minus mobo) is sufficient to run a game like WoW on medium to high settings, then I'd rather not upgrade everything. Thanks for any help/advice!
