Wanna buy new card, budget 100-120USD

[guest911]

Hi all I need your advice to choose a good card so please suggest me some good cards and give choices between AMD and nVidia as well as what max card my pc can hold without overclocking anything and botlenecking.

Here's what I've had purchased so far:
http://www.microdirect.co.uk/home/product/51178/asus-p5g41t-m-lx-bundle-with-intel-e5700-cpu--

I've replaced that ram with a Kingston 2GB DDR3-1333.

Also I'll change my PSU as well once I know what card I'm going to get.
IMO the max card my PC can support ATI's 5770 (don't know about nVidia) am I right?

Thanks for help.

Purchase date: this month.
Budget range: 100-120 without rebates.
Usage: GAMING! (Usually play quite light games like Killing Floor and Source games but should be able to run modern games as well, playing resolution 1280x1024 at the moment).
Current GPU and PSU: Had a XFX ATI Radeon 4650 512mbit 64bit had a good experience with it BUT with overclocking, should get a Corsair CX430 Builder-Series 430watts soon or anything you would suggest.
System specs: Already link'ed you to there (sorry but lazy).
Website: newegg (preferred).
Part ref: any ATI or nVdia but XFX, HIS, EVGA Asus is preferred respectively.
Overclocking: No. Since I read about WARRANTY VOID!

What makes you think that you can only support a HD 5770, you can support a lot better.

EDIT: I re-read it, nvm.

Re-read again, Not really sure what you could get.

Maybe you can tell me what is enough for my PC?

For gaming I would get another gig or 2 of RAM, and grab a GTX 550ti or a HD 6790 as they only require 1 6pin power cable.

and those aren't under 120bucks, aren't they?

I don;'t know, Im not from America or Canada, Im just relating them to UK prices, a HD6790 is around £100, so maybe if you look hard you can find one for $120.

nVidia just misses ya price point w/ the 550 Ti

GTX 550 Ti - http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&IsNodeId=1&Description=GTX%20550&bop=And&Order=PRICE&PageSize=20

That leaves ATI w/ the 5770 - http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&Description=5770&x=0&y=0
