Simply, will this card work and is it worth the purchase

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-h8/4507-3118_7-34742562.html )

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-FX775AZNP4-FX-775A-ZNP4/dp/B007Z3T5JC/ref=sr_1_18?s=pc&ie=UTF8&qid=1358051134&sr=1-18&keywords=amd+radeon+hd )

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

More about simply card work worth purchase
  1. 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.
  2. so what is the difference then? are they the same? it has me curious
  3. The 7750 will be a bit of an upgrade and should also be a straight forward plug and play swap.
  4. 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.
  5. Whats your max resolution?
  6. 1920x1080 i believe.. thats what my screen is now
