How much of an increase is DDR2 over DDR

[kweian66]

I have a 939 motherboard with an opteron 185 and 2 gb's of ddr 3200, I am about to buy a 8800 GT, and was wondering if upgrading to a new board and processor, so i can get some ddr2 ram, is going to give me any significant or noticable performance upgrades?

In short, no. Not really. Getting a new processor that's faster than your current processor would help you, but the performance will predominantly come from the CPU, not from any DDR2 RAM running in the system (per se). It's a little more complicated than that, but generally speaking, it isn't the RAM that you should be looking at here.

In "some" cases, you may be CPU limited so an upgrade to something like DDR2 800 and an OCed C2Quad 6600 would be a good idea. The developers of Crysis have stated that if you have a top end GPU and 4gb of RAM, the game can still become CPU bound with dual core CPUs. It stands to reason that future games will be equally or more demanding. So, following that route, C2Quad boards are all DDR2 or DDR3.
