Hi guyz,

I'm new to these forums. I recently bought a new Desktop and need help in buying the grahics card.

My desktop configuration is as follows:

AMD Phenom II X4 830 AM3
AMD 760G chipset - radeon hd 3000 IGP
6GB DDR3
640GB sata
280W PSU
Windows 7 64bit

This is a preconfigured system from Lenovo called the K305. I bought it cause I got a nice deal on it (500 bucks incl tax).

Now the 760G mb supports hybrid crossfire with the HD 3450. I have never used Crossfire or SLI so i have no idea how much of a performance boost that provides.

My question is, should I get a HD 4670 GPU and use it standalone or a HD 3450 crossfire(d) with onboard HD 3000 will give better performance ?

I choose HD 4670 cause it fits in my budget (~$50) and low power requirements. Also would I need a new PSU for 4670 or 3450 crossfire ?

I'm not a hardcore gamer. Would be playing games like COD modern warfare 2 or GRID or latest NFS or BLUR kinda games on 1280x1024 or 1024x768 res. I don't need very high detail either. I'm ok with medium graphic detail.

Please suggest.
Thanks for all the comments. I appreciate it.

Best solution

Hello and welcome to the forums
I don't recommend Hybrid CrossFire because its not for performance,its mostly for power saving and barely has an effect on gaming.
So go with 1 HD 4670,its much more powerful than 3450 HybridCF
And yes you'll need a new PSU for the 4670.A good 450W+ PSU would do the job

cool. Thanks!

Also, for a budget of $100, what would be my options for graphic cards+PSU combo ?

If I am getting a new PSU, might as well spend $20 bucks extra and get a radeon hd 5XXX .... makes sense ?

thanks anyway

Well for $100,its a little hard to find a decent VGA+PSU combo.Is it possible for you to raise it ?

1_Yes you need a PSU with a PCI-E connector
2_HD 4670 is faster than both HD 5570 and GT 240
3_As for PCI-E 2.1,its backward compatible with PCI-E 2.0
