and as far as a I can tell switching these slots out would solve your problem because i have 2 gigs of ram and a 2.0ghz processor and a single 880gts and i run full settings on both those games and have no lag what so ever.
hope this helps!
Um not exactly... What you're describing is the dual channel memory, which phenom IIs use. Like having a divided highway, so yes its best to split your RAM evenly between the coloured slots on your mobo. So 2gb in each colour is ideal, not sure how you ended up with 5gb though? Either way it most likely won't effect your frame rates at all.
You should be able to run those games maxed pretty easily. Turn down the AA a bit, should solve framerate problems. For an upgrade, a 5850 or 5870 would be a solid choice. Since that 9800gx2 is more powerful then a 5770. I can run mw2 maxed with 40-50 fps on a 4850 soo.
