Which part? The 750 ti is perfect for Dell and HP pre-built PCs. My Dell has an i5 3330 and 8 gigs of ram, so with the 750 ti its a decent machine. As far as games, I've bought too many in the last month. Steam count 1 (Free Portal 2 from PS3) to 200 (mostly bundles, some AAA.)
I apologize then. I'm not a big fan of the *50 line and didn't even know it came in a Ti, and then the whole throwing it in a Dell thing, didn't consider that they might fit well in a prebuilt, though I'd assume you could fit a *60 too. Oh well, my mistake and I'm sorry. Also, yeah, I've had my Steam account for like 10 years now, and when I went 5 years or so without it, then came back, I went from a few to a lot of games quick.
Since I was rude to you about your choice of card, check your PMs. I had sent it to another friend, but I doubt he'd use it or even redeem it. So be quick about it before his lazy ass reconsiders!
