Looking to upgrade my machine: HP Pavilion p6813w

Alvorix - RS880 motherboard
AMD Athlon II X4 645 cpu
integrated ATI Radeon 4200 gpu
6gb DDR3-1333 ram
250w psu
PCI-Express x16 slot for the new GPU card

Firstly please recommend a new gpu that I can drop right in. Done some research and the 6450 seems to be the most recommended, but those posts were years old and was wondering if there is something newer & better. As far as I can tell any card w/o an external power feed will work as long as it doesn't draw more than my 4200 does (20w). This would be used for HTPC and moderate gaming.

Secondly, how about recommending the full-blown gaming rig? PSU/CPU/GPU upgrades.

Thanks in advance!
 
Solution
Your best bet would be to replace both the power supply and graphics card. However, without changing the power supply, I'd only recommend the Radeon R7-240 or Geforce GT740.
