Second Opinion Needed on First Time Build

I posted this topic yesterday and was given two build options. (Thanks Why_Me) and I just wanted to get a second opinion if possible. I've posted the build options below. Particularly when focusing on the graphics card, which of the two builds would you recommend and what changes if any would you make? (I can go up to $800) Thanks.

ESTIMATED PURCHASE DATE: 1-2 Weeks

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Gaming, Watching Videos, General Use
PARTS NOT REQUIRED: Keyboard, Mouse, OS.

PREFERRED WEBSITE(S) FOR PARTS: newegg although not required

PARTS PREFERENCES: None

OVERCLOCKING: Preferably Not

BUDGET: $800

First thanks in advance for any advice given. Basically I am looking to build a gaming rig that can run most games coming out this year at full specs without too much trouble Games I'm looking at are Borderlands, CODMW2, and Dragonage, and L4D2. I'm not really concerned about hitting max specs for crysis though. I will unfortunately need to purchase a monitor along with the parts so I am including that in my $800 budget (I might be able to to be a bit flexible though.)

Like I mentioned before, this is my first time building a PC so I really don't know where to start. Any help would be greatly appreciated.

I should also mention that I can pick up a copy of 64-bit Windows XP for cheap from my school. Would this be recommended?

^ The PSU and the video cards are present in the list...they are in the combos...

And @Ronny77 the 1st build is better than the 2nd for these reasons -
1. Faster graphics card.
2. Far better PSU.
