Upgrading video card from onboard to PCI Express?

Alrighty, I've read this Q&A, and added 2 comments but nobody replied to them.

I've got the same computer as JP who asked the question.



I also discovered this graphics card:

So my question in detail is.. .What do I need to know if I want to upgrade? Will I have to buy a larger power supply? Will I need to install extra fans or some sort of cooling system?

Will my motherboard even support this GFX card model? (I don't know what motherboard I have and don't know how to figure it out)



I'm lost with this technology, and really want to be able to experience DX10 games, and replay games I can no longer play...



Thanks so much in advance = )|||Need to know:

1. Do you have a x16 PCIe slot and enough space on your motherboard for that monster card? It will cover the space of another PCI slot.

2. Do you have a Southbridge chip that is positioned closer to the middle of the board instead of towards the edge? Does it have a tall heatsink that could obstruct the card?

3. Do you have at least 26 amperes on the +12V rail of your power supply? That card draws up to 9 amperes on the +12V rail.

This one should have no trouble powering a PC with that card:
