Right now, I have an 8600 GT, P4 3.4ht, one SATA hdd (I have a 4-pin to SATA converter), one IDE hdd, and 2 IDE disk drives. I plan on getting an 8800 GT if it is close to as good as the hype makes it seem, and will eventually get a Core2 (or if AMD shapes up, on of theirs. Either way, something that will use much less power). That will be down the road, probably around 6 months. I was first wondering how much of a bottleneck my CPU will be. I know there's nothing official, so using an 8800 GTS for reference would be fine. Second, I have no clue what I need for a PSU, my current one is pretty bad, an Enlight 300w (I think). I just wanted to know if there are any reasonably priced (read: sub-$50) PSU's that I can use, or if mine has any chance in hell of running with an 8800gt. I also have a few generic 450w PSUs lying around, but I don't think I should trust them.
