I'm looking to buy a new graphics card for gaming. Here are a few specs on my system
Radeon HD 6450
Intel 2nd Gen Core i5 2 i5-2390T / 2.7 GHz
8GB DDR3 SDRAM


Here's the rest of my system specs ( http://reviews.cnet.com/desktops/hp-pavilion-elite-h8/4... )

The new card I'm looking at right now is an AMD Radeon HD 7750 (1GB) heres a link:(  http://www.amazon.com/XFX-DisplayPort-PCI-Express-FX775... )

1. My computer, according to that website only has a PCI express x16 and amazon says the 7750 is a PCI express 3.0 x16. So I am wondering what exactly....is different? Will it Fit? Will it decrease performance? Is it worth the money? Should i get an Nvidia or different radeon? or should i just build my own custom computer?

i know its a lot to ask but im not exactly an expert as you can tell... :sweat:  im open to any suggestions so feel free. im hoping to get a lot of helpful feedback. thanks =D

Hd 7750 really a good upgrade from hd 6450.pci exp 3.0 is backwards compaitable with 2.0 and 1.0 mobo.they are all of same size.there will be no performance loss.

The 7750 will be a bit of an upgrade and should also be a straight forward plug and play swap.

They operates at different speed like pci 1.x at 2.5gbps,pci 2.x at 5.0gbps and pci 3 at 8gbps.even if you get highend gpu like hd 7970 even it will not utilize even pci 2.0 speed.you donot have to worry anything.
