Hello everyone, newbie techie here. I'm looking to upgrade my graphics card (hopefully without upgrading the PSU), but I'm not quite sure what I need to look out for to make sure my purchase is compatible with my computer. My Specs: -Intel Pentium 4 Processor (1794 MHz) -Motherboard Manufactured by Dell, Model:07W080 -1024 MB Ram -And I -believe- my PSU is 250 watt. I'm looking to spend around 50$, but I could go up to 75$. If you have any other upgrade recommendations, particularly in reference to the motherboard or PSU, they are most welcome. Thanks for helping a noob!
