right now i am running 2 sticks of 256mb each of the mwave brand memory which is ddr400 pc3200. so all in all i have 512mb of memory running on an asus k8n motherboard with an amd 64 3000+ and a radeon 9700 pro graphics card. my question is, i want to either upgrade the memory or the graphics card for gaming, so what should i do first? would it make a big difference switching memory to say a gig of kingston or corsair? i can only do one right now and memory would be a bit cheaper, but what should i do?
