I bought the HP DV7-2185dx which has a Quad Core Q9000 processor in it. They just replaced this system with the i7 processor. Is it worth exchanging it for this new one. It wont cost me anything just the time of taking the stuff off this laptop. It also had a 7200 RPM HD instead of a 5200 RPM and it had NVDIEA graphics card instead of ATI.

The i7 is better without a doubt.
if it costs u nothing then go for it,i7 is better no doubts about it,however if u are going to game then check that what GPU u have currently and what is going to replace it
