Hi everyone, I'm not too good with computers and was hoping you guys could lend me a hand . I have a MSI G31M3 LV2 Mother Board, Intel Duo Core. I was wondering what is the best video card i could purchase at his point given that it is a PCI-E port 1.1x16 . I know PCI-E 2.0 is compatible with 1.1 but will run at 1.1 speed but i just want a video card that wont be bottlenecked by my cpu or motherboard too hard . I was looking at this "AMD Radeon HD A5450PE3512 512MB GDDR3 PCI-E" and it seemed decent . Any suggestions ? Also my motherboard holds DDR2 ram, does it matter if i buy PC2-5300,6400, or 8500 ? Or are they all the same ?

Thanks so much for your help, I appreciate it .
