Is this cpu/gpu good enough for these games?

I'm wondering whether a 3.2 ghz intel i5 quad core / nvidia gtx 760 1.5 gb will be enough to run wildstar/ffxiv:arr on high (ultra?) with minimal lag?

Yes:

Thanks!

I'm wondering if it's overkill now... cheaper alternatives include:

3.2 ghz intel i5 quad core with a nvidia gtx 745 2 gb

2.9 ghz intel i5 quad core with a nvidia gtx 745 4 gb

3.1 ghz intel i5 quad core with a nvidia gtx 645 2 gb

If any of these can run wildstar/ffxiv:arr on high (ultra?) I should probably choose one of them, any advice is appreciated.

You might as well just go with your first one

Stick with your first build, it will run it really well and will be more useful in future to run any other games that take your fancy.
