Need a budget gaming gfx card

Okay, well I've been working really hard over the past few weeks and I managed to get a sum of $320.

I live in Canada, so I cannot order anything from newegg.com or I'd be okay right now.
I currently have my pc setup as follows :

E6300 2.8ghz dual core
ECS G41T-M(2.0) LGA 775 Intel Micro ATX Motherboard - I believe this supports PCI-E 2.0
Crucial Ballistix 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit
APEVIA ATX-CW500WP4 500W ATX Power Supply

Now, the only thing left is the graphics card....

I've been searching and searching, and I found a couple that I really liked but I've heard mixed reviews of them...

Here are my top 3 choices, but you can suggest another card if you believe these are all bad for gaming...the max I am able to spend is $65 on the card, and only if it has a rebate. If it doesn't have a rebate on it, then the max I can spend is $55.

Here is the first card :

This one seems to be really good.
9600, meaning a decent ranking. 512mb GDDR3, which is always good.
It seems like it's a 128bit. Decent memory and core clock as well...so yeah.
Only thing about this one is that people said that their scores for graphics were 5.7 on the vista rating, but other cards (such as my 3rd choice card) performed much better, having a score of 5.9.

Second Card :

512mb, GDDR3, 9500 GT....Same as other one, just $5 less on the rebate, so basically $5 more expensive. Don't know whats good :|

Third Card ( my choice, imo the best one )

http://www.newegg.ca/Product/Produ [...] 6814143066

I had this one on my cart then deleted it and then 2 days later they ran out of stock. Figures.
Anyways, this one is a 512mb GDDR3 **256-bit**, the only 256bit card on newegg not over $200 lol.

I believe this is the best one, for its price and for its performance. People say they got 5.9 vista rating for gfx, and that is REALLY good.

I won't be playing "new games" with the cards, so if you can find a really good card that can play games fairly recent , but nothing like Crysis or Far Cry or Bioshock...

Just normal games that are really popular like COD4, WoW, etc...

Thanks!

I like my 4670

Mine is from newegg, but I am sure you can find one like it from a company up there in canuk land.

I play the same type of games as you and love it. It is very energy efficent, decent performance, and stays very cool.
