New customer and PC gamer - some vet advice?

First off - so glad to be jumping into the DS community.

In the late 90's, I made the switch from PC to console gaming (I know, I know). Now I'm making the belated switch back, and am completely out of my element!

Anyways, today I ordered the ODE V2 level 1 - I figured it would be a good starting point. I tend to play games for a very long time (for instance - I still regularly play CS:S [on my MBP!]).

I would like to hear you vets' opinion on 2 things.

1: How well can I expect to run Diablo 3, Guild Wars 2, and CS:GO on the ODE V2? Those are the only games I care about for the far-flung future.

2: If a game releases in the fall that I get amped about, but my rig can't handle it at the preferable settings, which component of the ODE V2 should I upgrade first, and with what? (Or, will it depend on what kind of issues I'm having?)

Thank you guys (and gals?) so much in advance. Have a great day.

bprat - that helps a ton. Thanks!

I actually don't have a monitor; I was planning on using one of my HDTVs (46" LED or 27" LCD). I've read/heard varying things about using that kind of a setup. What are the pros and cons?

It will look pretty much the same as gaming on a console ..Pixelated.
If the funds allow, get yourself a DellU2410.

I too have the U2312HM. Love it. You can get it for a pretty good deal on some sales though.

The color difference is soo noticeable though. Like its really cool.
