64-bit Windows XP has a very bad reputation. If you want to go 64-bit, switch to Windows 7, assuming it supports the applications you run.
Assuming your case, disks and graphics card still are OK, you can indeed consider to buy a new motherboard/CPU/RAM-combination and install that (or have it installed by the shop). Depending on the graphic card, however, it could be that the new motherboard doesn't have the right slot for itl then you would have to replace that also.
I'll leave recommendation for possible mobo/CPU-combinations to others. Not my cup of tea.
By the way, in a recording studio I'd expect a good quality sound card also. You don't mention that.
Hi Techs -
I have a computer in my recording studio that was custom built by INTA Audio specifically for Music Production. I really need to upgrade it at this point because it's beginning to struggle with some of my programs (program updates are putting more strain on it). My computer needs to be fast, stable, and needs to have a fast refresh rate on the graphics. Oh, and I need to be able to do this quickly as it's holding up studio jobs (read: MONEY).
The computer is as follows:
AMD Athlon64 3700+ (2.4GHz)
3GB Corsair RAM
Radeon 9250 Dual Head graphics card
500GB Sata Program Drive
500GB Audio Drive
Custom Acoustic Silencer Case with high quality 500W power supply.
Windows XP Pro (SP2)
I would like to keep things like they are with respect to using Windows XP, except that I think I'd like to upgrade that to 64-bit in order to take advantage of more RAM. I also want to keep my case....so I'm HOPING that a multi-core upgrade will fit in my current case.
Can anyone please advise on what motherboard and processor combination to look into and suggest some upgrades pertinent to what I use the computer for?
