Whats your budget? I'd look at the r7 265, r7 260x, r9 270, or gtx 750 ti

500-600

I cannot find the specs for you mobo :/

 

[marooner]

Honestly, your build is so old you'd be better off upgrading your entire system.

Idk. There's so many things that Id like to upgrade with this that I think your better off with spending that $500-$600 on a new computer. I can give you a build list if you want.

 

[almanacoftime]

Okay, I like to see your build list please (please don't rec me to buy a new case cause I don't like putting items all over)

This build will run most games at least high and some on ultra. It also features good upgradability. I didn't include a case like you asked

 

[almanacoftime]

If I changed my mind to get a case, what would you recommend?
and by the way I said I don't like put it all over is like connect this, connect that

 

[DroneDroneDrone]

This is cheap and nice case : http://www.newegg.com/Product/Product.aspx?Item=N82E16811517027&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID=
You will have to "connect this and that" you can't avoid that. Even if you're just upgrading your current pc you'd have to disconnect and connect stuff. You could always pay a computer shop to do it for you if you really don't want to
