[Frankjones]

I bought my computer last july and I would like to buy a graphics card for it. I have been looking at the ATI Radeon HD 3870 512MB GDDR4 PCI-Express Video Card but i am not really understanding the pcie slot differences and compatiblities. I think I have a 1.1 but I am not sure and the card is 2.0 would the card work in my computer and will the performance cost be.
My computer is a
Acer Aspire E700 R01-A4
System Serial Number: PTS590X014721090602701
Board: Acer FG965M
Serial Number: 04EF64900146
Bus Clock: 266 megahertz
BIOS: Phoenix Technologies, LTD R01-A4 03/26/2007

If anyone could please help me that would be great

Hi Frankjones and welcome to the Anandtech Forums.

Thank You could you also tell if there will be a signifcant performance loss and is it worth the extra money or would it be better just to buy a pcie 1.0 card

PCIe 2.0 basically only adds additional bandwidth to the bus. You won't have any performance loss.

what power supply is in the Acer? Make sure it has enough power for the card you choose.

I have a 300W power supply in right know and it doesn`t have a 6 pin connector so I was planning to upgrade to a 600w power supply which should be enough. Thanks for the heads up and all you help
