I just realized I'm friends with none of you guys on steam - ADD ME (even though I can only play TF2 and LoL right now )
Well if you can run tf2 you can definitly run dota 2. You should at least try it. And by try it I mean play 100 hours.
I have tried, I lowered it all the way and got 5 fps while I get 25 in LoL. TF2 is an odd ball for some reason and I can play it at a solid 30 fps in most cases. Butt, you're talking to a man who's first MOBA he cared about was DOTA and then due to my computer done dying in December, I had to learn how to LoL(which I can now play with 1 hand and rek)
