4350 is the 'x3xx' series GPU. It is a low end GPU, and 9800GTX is a high end GPU because there is GTX written there and it is x8xx/x8x series which also shows that it is a high end.
But if you want 9800gtx, don't buy it now. Buy something better like GTX 460 or 6850.
Thanx for the feedback !!!
I will invest in a GTX 460 then
