I have a GTS 250 that I purchased a long time ago. Im sure this card is crap compared to what is out now, but I could get another GTS 250 for around $35. I wanted to build a new machine, but am In college and lacking funds to buy a high end video card. My question was, what is the single card equivalent to two GTS 250s running in SLI? I just want to have an idea as to how well it would perform compared to a more modern card. Thank you!
