Hammers or scammers?
6200 LE?
Now, I know that the x1650 is no screaming speed demon, but it can still turn in a respectable performance.
But the 6200?, that's really somewhere near the bottom of the gaming food chain.
Those guys in the store are either dumber than an bag of hammers or are just a bunch of scammers.
Refering to the October hexus 2006 review of the x1650pro review (ATI Radeon X1650 PRO 3-way shootout), you will see that the x1650pro is comparable to the GeForce 7600 GS.
you need to march back to that store and demand that they change if for at least a GeForce 7600 series or ATI x1650.
The way graphics cards are numbered can be confusing, but stating the way I have should leave them in no doubt that you know what your talking about.
Good luck.
