Hey guys, i recently built a gaming computer, it runs everything really well. I got my video card from my friend, and I have been wanting to upgrade my videocard. I have a 7770 and it runs games great, but I want to save up and hopefully by summer time I can buy a 7870. Only thing is i know video cards run out of date fast and was wondering if its not worth getting the 7870 and instead saving up more until I have enough for an r9 card. Just curious on if I should buy a 7870 or not, thanks.
