AMD Radeon 7850 HD

Hello everyone!!! I just finished off my high school and I'm off now to serious gaming. My present PC config is as follows:-
☻Intel Dual core processor
☻Intel DG31GL motherboard having Intel G31/33 chipset
☻Transcend 4GB DDR2 RAM
☻Seagate 500 GB internal HDD
☻Frontech 450W PSU
☻LG 17" TFT LCD (85Hz 1440x900) monitor
☻a stupid old computer case

But the problem is right now I can only spend $ 320.So I'm thinking of taking a Asus G41 chipset for $ 80 and the Gigabyte Radeon 7850 HD.I don't want to upgrade my processor and RAM 'cuz that would push the budget high up.
I'm also taking a new mobo as the existing one does not have a graphics card slot(and I'm not pretty sure of that,the shopkeeper came and told me this after inspecting my PC).
As the Pitcairn pro supports reverse compatibility, so it would run on a PCIe 2.0 mobo without any problem or any noticeble performance lag.Kindly anyone and everyone suggest me what to do next?Am I okay with my decided upgrade?

Please do suggest me a basic mobo for LGA 775 socket for Intel Dual Core processor(2.5 Ghz),DDR2 RAM.

What about a mobo with crossfire? Eventually you could get another 7850 in a year or two and greatly increase your performance? Crossfire is more attractive now that these cards (especially the 7850) has a low watt draw.

For a system using a reference clocked single Radeon HD 7850 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 24 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important factor.

The Frontech 450W SMPS, with its +12 Volt continuous current rating of 20 Amps or less and with no PCI Express supplementary power connectors, is insufficient to power your system configuration with a single Radeon HD 7850.

You're going to need a new power supply with enough capacity to be able to properly power your system with a Radeon HD 7850.

Well, for now I'm not thinking of Crossfire 'cuz my budget is xtremely tight.Yet can u tell me the cheapest dual PCIe slot mobo right now?I am not focussing on overclocking,so leave that out.Suggest something cheaper than ASUS P8P67 B3 revised edition,'cuz I'm going to continue with my LGA 775 Intel Dual core processor and DDR2 RAM.

Nywayz,thanx for the help!http://img.tomshardware.com/forum/uk/icones/smile.gif

Yeah,I know that.but can u tell me will Intel's DG41RQ board be able to run the HD 7850??
Thanx for replying.

There's no technical reason why it can't run.

The motherboard's Intel G41 Express Chipset supports the older PCI Express Revision 1.1 so your PCI Express bus bandwidth (8 GB/s) isn't going to be the greatest.
