Need Advice, Asus or Sapphire HD 6670 DDR5 ?

[Ambujkoshi]

Hello! I'm new to this forum. I'd be really glad if someone helps me with this.
I haven't upgraded my Graphics since so long. It's time!
My PC Specs :

AMD Athlon™ II X2 240 Processor 2.81 GHz
2 GB RAM
GeForce 7025 / nForce 630a
Motherboard

Can anyone help me upgrading this to a entry-level PC. Also, I'd probably be buying 4 GB RAM too.

1. Shall I go for AMD or NVIDIA for a Graphics Card? Afaik, AMD is comparatively cheaper, and gives a value for money.
2. I'd buy Graphics Card which supports latest games like BF3, Assassins Creed Series, COD, BF4, NFS etc.
3. I've seen searching throughout some forums and stuff. And found the following suiting me and my budget :

• 
  ■ Asus AMD/ATI HD 6670 1 GB GDDR5
  ■ Sapphire AMD/ATI Radeon HD 6670 1GB DDR5

Also, if possible can anyone suggest me more Graphics Card?
My budget is 100$ for this and I'd be buying one at this month's end. Any other suggestions are welcomed. Thanks

Asus 6670, go for it!
There's another card, a whole lot better than the 6670.. Its the 7750.

Thanks.
Btw, would I be able to play Crysis, Watch Dogs and some latest game titles?
I have planned to get myself a Graphic Card this November, choice being Asus 7750 or Asus 7770.

7770 is a whole lot better than the 7750.
But for the 7770, you should have a pci-e connector in your power supply.
