I would like to upgrade my processor.

Specs: Windows 7
Hello all. This is my first post, so here goes:

I would like to upgrade my processor. My motherboard is from a Dell Optiplex GX-280 and my current processor is an Intel Pentium 4 (3 GHz). This is my first "custom build" (some components came with the old computer), so I may be missing details in this post and not even know it. This is the last upgrade I plan on doing for this computer, and I have no idea where to start when shopping for a replacement. Any help would be greatly appreciated.

Before anyone says it, yes, I know it's an old build, but it's what I'm going to be using for the next couple of years.

Again, thank you in advance.

According to DELL it uses a Grantsdale Chipset aka 915, and supports the following:


Go to left hand menu, compatable products / processors

It seems that you have very little options. best to start afresh...

or choose yourself separate components (even better).

You have to be a little bit crazy to keep you from going insane.

Here's the corrected link:


Your board/chipset is old/outdated & doesn't support modern dual core processors. I don't see much point in upgrading the CPU unless you can find one extremely cheap & even then, I doubt you'd see much of a performance gain.

There were different versions of the GX-280:


The tower accepts up to 4GB RAM ( 4 x 1GB), the SFF only accepts 2GB (2 x 1GB). Regardless of which one you have, you should max out the RAM amount.

Your board should have a PCIe x16 slot for graphics, so if you're still using the onboard video, you may want to add a cheap PCIe video card. If you don't play games or do anything graphics intensive, you won't have to spend a fortune. Intel onboard graphics suck, they steal RAM plus put a drag on the CPU. I wouldn't recommend anything too high end unless you're willing to upgrade the power supply. If you have the SFF system, you'll have to get a low profile card.

I've maxed out the RAM, and installed a NVIDIA GeForce GTS 450 video card. I've upgraded the power supply, and installed new hard drives. A lot for an old computer, I know, but I plan on a fresh build in two to three years and intend on using all of those parts again. I was just hoping on eeking out a little more speed in the mean time.
