Will my computer support this graphic card?

[poeticdevastation]

I'm trying to buy a graphic card tomorrow and im pretty new to the whole computer modification thing so im going slow by getting a low grade Gfx Card.
The card im interested in is the -- ZOTAC GeForce® 8400GS 256MB DDR2 (667MHz/1400MHz) PCI-E Video Card [ZT-84MEG5M-HSL] or the -- GeForce 7200 GS 256MB (512MB TC) 64-bit GDDR2 (450MHz/533MHz) PCI-E Video Card ZT-72SEG7N-HSL.

My specs
Windows xp home edition service pack 3. (don't know the bit)
Amd Sempron processor LE-150
2.01GHz, 2gb of RAM
Motherboard - ASROCK - AliveNF6P-VSTA
PSU Wattage - 350W
Regular plug and play hp monitor

so which one will be right for me. If i have to ill upgrade my PSU other than that budget is at a crunch.

also i my PCI express slot os only x16 and not 2.0 which the Zotac Gforce 8400 requires so will this be a problem. Id appreciate the help.

Thanks

Hmmm....both are very low end.

What do you have for graphics card now?

I would seriously consider upgrading the entire computer.
