I just built a new computer and I'm pretty stoked about it. It is so fast.
Intel's Q9450 2.66G processor. I'm used to having a single 2.0 ghz core, and now I have 4 2.66's! Crazy fast.
Also got my hands on the GeForce GTX 260 - video games look so awesome!
I've only used it for about 2 hours though because there's just one problem; I left my battlefield 2142 key at a different base. LOL So I'm still using my old computer because i HAVE to play battlefield 2142. What I did do with my new computer was pretty sweet though - It tears through rendering.
I loaded a project I did a few months back that I know took a long time to render with my old machine - rendered it on the new one and it was so fast. Ate it up and asked for seconds. lol Im pretty happy.
