XFX ,MSI, Sapphire: HD4850 vs Sapphire HD 4830 vs Which one to choose?

[Wayne]

Hi guys..
Well, i have brought a processor + memory + mobo.
I am not good at taking decisions, i dunno which i should pick :S
I'm not going to overclock, i'm going to stay at stock values.
Current specs:
PSU C3 Tech Dsa5060 600w (500w real power)
Processor Athlon 64 X2 7750 2.7 BE
Motherboard ECS A740GM - M
Memory Markvision 2GB


HD 4830 is cheaper than HD 4850, but, XFX HD4850 has a bad cooling system, and is better than HD 4830.
Let's see both video cards:
HD 4830 Sapphire

XFX HD 4850

Now, the HD 4850

I'd go with XFX. They are reliable manufacturers of graphic cards from my experience.
