Last week I decided to upgrade a few pieces of my PC, as they were over 18 months old, and therefore obsolete.
After getting some new RAM and a video card, I found that my case/motherboard situation didn't have enough power to keep everything alive, so replacements of those were required, along with a CPU.
After all that, I ended up with the following beast:
Gigabyte K7 Triton Motherboard
Athlon XP 2800+ running at 2490 MHz (2.4 Gig) CPU
1G of DDR Ram at 333MHz (Dual Channel)
ATi Radeon 9800 128MB 3d Video Card
...
and other stuff.
(oh, and the case has boy-racer neon tubing. The photo doesn't do it justice.
)
