I have an old HP 1720n. Apparently, from what I have been reading online, the oem motherboard is not compatible with pci express 2.1 or 3.0 since HP did not make any bios updates available for it. I need a video card, the cheaper the better, that will allow me to play DotA 2 on medium to high settings. My power supply is only 250w.
Any recommendations would be greatly appreciated. Cheers!
