The GPU is a Radeon HD 4670 1GB 128-bit DDR3, PCI-E 2.0 x16, but I already asked about it on yahoo answers and the answers seemed to agree it will work(the motherboard only has a PCI-E x16 slot) http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Apparently, it has 1 gigabyte of K3-PH, whatever that means, and googling it doesn't seem to turn up anything....
Now I was wondering if I needed a new power supply, and if I do, what would be the minimum amount of Watts and output voltage would it need to operate without frying my computer on startup...my current power supply has 250 W, with a fixed voltage of 100 to 120 Volts at 60Hz and 200 to 240 V at 50Hz
If i did need to get a new power supply, would I need a PCI-E connector? I've tried Googling it several ways, but can't find anything.
Thanks for any answers! I'd also gladly take any suggestions (as long as it doesn't starve my wallet).
You might want to follow the guidelines from the link in my signature. If you give us a budget and other information, we can certainly give better advice.
You will certainly need a new PSU. Dell uses very cheap units which are very poor quality. In addition, 250W would only power a very bare bones system. That wouldn't even run a discrete GPU, much less one that requires a PCIe connector (which you do need).
