Without knowing your motherboard make and model, we can't say with 100% certainty.

You should have no issues doing so, specially if your PCIe is a PCIe 2.0 x16. If it is just PCIe x16, you might bottleneck your GPU slightly but still will be much more powerful than the 8800GTS 320M.

Hi newcomer and welcome to the Tom's hardware forum.

Yeah u can upgrade the GPU and keep the rest BUT bear in mind that the games performance not only depends of the GPU u also need have a good CPU and a good amount of RAM to get good FPS.

You may want to check your Power Supply Unit, to see if it can handle the 5850.

The video card should list power requirements.

Hopefully Asrock has bios updates so you can move up to an Athlon II X2,3 or 4 to take advantage of a new GPU!

I have an Antec 500W PSU that I purchased 1 year ago. I wonder if it will do. It was suppose to be a good one.

Here are the system requirements for the 5870:

ATI Radeon™ HD 5870 System Requirements

PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard
500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in dual mode)
Certified power supplies are recommended. Refer to http://ati.amd.com/certifiedPSU for a list of Certified products
Minimum 1GB of system memory
Installation software requires CD-ROM drive
DVD playback requires DVD drive
Blu-ray™ playback requires Blu-ray drive
For an ATI CrossFireX™ system, a second ATI Radeon™ HD 5870 graphics card, an ATI CrossFireX Ready motherboard and one ATI CrossFireX Bridge Interconnect cable per graphics card (included) are required


The recommended PSU is for the entire system, so, ur PSU can support a single 5870.
