So I was getting ready to buy that rig I posted about earlier, when I found two things that made me realize how stupid I was/am.
1) DDR3 is a waste of money. The CAS latencies are just too high to be effective. Effectively, DDR2 is just as fast due to CAS latencies of 4 and below. The only difference seems to be a few FPS and a ton of money.
2) Most people know that the CPU/RAM should have matching FSB or else you get a bottleneck somewhere. CPU being too fast makes the RAM and a bottle neck and vice versa. What I didn't realize is that duel channel effectively doubles your RAM speed. Meaning if you have 1066 speed RAM, you need a 2000 MHZ FSB on your CPU to get any use out of it (you'd need to overclock it). So unless you're a hard core overclocker with a water cooling system set up, there's no point in buying anything faster than DDR 800 (giving you some headroom since apparently that helps).
Anyone else notice things like this?
