I really need some help here. Basically I want to use my computer for newish games (nothing like Oblivion or whatever), but mainly for graphic design and my music production. At the moment I get a lot of memory and CPU errors when loading instruments and recording, due to my low specs:

P4 2.4GHZ
512MB+256MB RAM (I think at two different speeds as well)
ATI Radeon 9800 Pro
250GB WesternDigital HDD

So basically, I don't want to spend a huge amount on parts, but enough to get it back into shape. Otherwise I'd just continue to save up for a whole new system.

-Would it be wise to upgrade the CPU to a P4 3.4GHZ? The newer CPU's like Duo 2 Core are way too expensive, but I don't know if there might be something better for a desktop.

-Also, I am going to get these sticks of RAM that we had figured out in an old thread not long ago.

-Last of all, I was thinking of just getting this as I only have AGP and not PCIe slots, for my graphics card.

By the way, I have no idea how to install a CPU, but I know how to install video card, ram, HDD's, and optical drives. However, I did download CPU-Z to get information on my CPU and motherboard. CPU is Socket 478 mPGA, L2 512KB cache, 800Mhz FSB 200Mhz Buss speed. Motherboard is IBM, Intel Chipset i865P/PE/G/i848P, Southbridge is 82801EB (ICH5), Sensor SMSC 6B81, Version 2AKT32AUS, AGP Version 3.0 8x.

Sorry this is a long post. >.<;
