Hi! It's me again haha. Well, if I were to get a EVGA 256-A8-N542-T2 GeForce 7600GS 256MB 128-bit GDDR2 AGP 4X/8X Video Card, would I need to upgrade my OEM Dell PSU? It's 250W I read the review on this card and some people said they needed to upgrade to a 600w PSU and others said they upgraded to a 350w PSU. Does anyone know which PSU would be compatible with my compatible with my computer? I have a Dell Dimension 4600. I heard that Dell has been known to use proprietary parts. Also with this upgrade of video card and or power supply, would I need to upgrade my Motherboard or CPU? Or even the case? Because some of the PSU's havea fan on top and my Dell doesn't have an opening on the top for a fan. I'm running 512MB Ram, 3 GHz, Intel Pentium 4 Processor, Windows XP. Thanks!
