When I purchased my system about 2.5 years ago I new absolutly nothing about PC's. Well ive learned a little and am going to brave the building world. My situation is this, I want to go with a DDR system but crucial doesnt make 256MB sticks of 2100. I want at least a 256 and hope for 512(2 sticks). My question is this, everyone says go with crucial, well they don't make 2100 256MB DDR right now. I only have till April for things to change and im getting worried. Why is brand name so important? If i find a let say genaric 256MB 2100 DDR and it has low latency why is it not as good as the name brand ones? If I cant get this worked out I will have to go with a PC133 system, which I dont want to. I mostly play games but use programs such as solid works also.
