Asus 650ti 1gd5 or evga 650 super clocked which one?

Hey I'm looking to buy a budget Pc and I'm a little confused a bout which graphic card to buy so if any one can answer I'll be really great full....the specs in my pc are gonna be:
Intel core i3
Pci-e 3.0 supporting mobo(forgot name)
Parvum case (already have)
250gb hard drive 7200rpm (budget )
A Samsung DVD writer
630w thermal take smart se PSU
Windows 7 home prenium 64bit
But overall my biggest concern is the graphic card...what attracts me towards the 650(non ti) is that it is sli ready so in the near future I can add another but some people say that the performance of a 650ti is better ..... And just per say I'm a guy who plays assassins creed and COD not battle field...
I'll be really great full to any one who answers me with a good reason for either cuz my time is running out!
Thanks in advance

And also the 650ti is 1gd5 not the 2gd5 boost... Also if you could name a graphic card better for same price it would be cool as well! My main game on my consoles were ac4!
