Just ordered 2GB of Ballistix Tracer RAM, 2 x 1GB sticks to give my Athlon64 x2 more RAM to use. I had 2GB before, but when you fully populate all 4 banks the speed drops to DDR333 and I didn't want that. So doing it correctly this time with 2 sticks. I just picked up "Intro to 3D Game Programming with DirectX9c a Shader Approach" by Frank D. Luna great book so far. Covers it all, from math to Shaders. Drops the FFP to get one ready for DX10.
