I have a Pentium 4 2.66 Ghz on the mainboard P5GZ-MX of ASUS. Now I am using an Intel Integrated VGA and I want to get a new VGA. I've found MSI 4670 which I was consulted by members of other forums (and probably I can afford it) but I wonder if the bottlenecking problem would happen to my system. Please give me some opinions. Thanks all.
