Hi Guys, As you can see from my signature I have 256 MB of RD-RAM.I do all kinds of stuff on my computer - AV encoding,3D graphics,Programming with real Memory stealers like Oracle [ 9i and above ] ,.NET and so on.So I thought I would upgrade to 512 MB of RAM.But PC800 RD-RAM at 800MHz alone is available , not 400 MHz.My question is : 1 . Will the RAM run on my Mobo ? I tried all kinds of customer cares with no reply. If there is no RAM available my brother suggested me an upgrade of the following components alone : CPU , MOTHERBOARD and RAM and GRAPHICS CARD [ I admit I also play some games ]. Is it the right time to upgrade now ? or should I wait for some more time before the market stabilises as I do not want an upgrade atleast for the next 3 to 4 years. If u think it is right to upgrade can u suggest me the best configuration for and AMD ATHLON 64 FX based system under 20 - 22 k with the above mentioned four components alone ?
