I posted a topic about the EVGA GeForce GTX 470 Super Clocked 1280 MB DDR5 PCI-Express 2.0 Graphics Card 012-P3-1472-AR, and right after realized that the Graphics card is a little bit too much money. Anyways, I am now looking at a XFX Radeon R7 250 (R7-250A-ZLF4) 1024MB PCIe x16 Gen 3.0 and I kind of have the same questions. First off, can I run it. Newegg has the details of the Graphics card and its requirements: http://www.neweggbusiness.com/product/product.aspx?item=9b-14-150-682 Here's my system info and my current graphic card info Second, I will need to get a new PSU as this requires 400W, and my current PSU is only 250W. Should I get a PSU with 450W or should a 400W work fine? What PSU do you think I should get as I am stumped. Also, if I replace my computer's PSU, will I run into any complications? Third, I believe I have a PCI e x16 (ill post a picture just in case I actually don't have one) and this Graphics Card says PCI e x16 Gen 3.0. What exactly does that mean and will I run into any problems if I install it? Lastly, what other things do I need to take into consideration as I think about getting this Graphics Card?
