In DIRE need of a new GFX Card, need advice

Okay so I've got a 9800GT 512MB at the moment, I've had it since Nov 2008 when I bought this PC, it's pretty much crapped out on me, so I'm looking to buy a new card, I'm no enthusiastso my budget is about $150, here are the cards I've been looking at on Newegg

http://www.newegg.com/Product/Product.aspx?Item=N82E16814130514- $140 after rebate+shipping seems pretty good to me, no idea about the "2 free dl games," can't say I care to much.

http://www.newegg.com/Product/Product.aspx?Item=N82E16814150439- $150 Seems almost identical to the EVGA card, although this ones "Effective Memory Clock" is 2000MHz instead of 2200MHz, it's also $14 more, my friend just pointed it out that it comes with CoD 4,

http://www.newegg.com/Product/Product.aspx?Item=N82E16814133266- $110 after the deal+rebate, seems very standard, I heard their customer service is garbage, haven't heard the same about XFX or EVGA.

So I'm wonder what the best buy would be, I don't own a ton of graphics intensive games and the ones I do own I don't play often Gameplay>Sexiness, at the moment I'm leaning more towards the EVGA one, partially due to the fact I've heard they have a good warranty/customer service, and I read somewhere that they're mad easy to OC with some provided tool.

I also don't know much about ATI cards, I didn't look into them much.

Current specs:

Intel Quad Core 2.5Ghz

Nvidia 9800GT 512MB

8GB of Ram 667MHz (got it for dirt cheap :) )

400Watt PSU (I have a 600Watt PSU, just no need to put it in at the moment)

I have no clue what motherboard I have, sorry.

dude...They're basically the same card

I thought they were going to be 3 different cards

XFX

$154 is within shooting range of the 5770. Totally not worth it IMO.

yeah 5770 all the way.. the factory oc edition pick fights with a gtx 260 alot of the time grab a vapor-x 5770 or a pcs+ and go crazy baby. why not maximize your effort lol.

no doubt a 5770 would be the best choice at that price point.
