Upgrading From Embedded Video Card

System: HP Pavilion p6310f Desktop
CPU: AMD Athlon II X4 630 @ 2.8 GHz
RAM: 6 GB PC-8500
PSU: 300 Watts
VRAM: nVidia GeForce 9100
PCI-E: x16 (1.1)
Windows Desktop Experience: 4.3

Looking to upgrade to discrete video card to improve performance.  Typical usage activity includes: HD video playback, light video editing (Win Movie Maker), older PC games (CoD:MW), web surfing, and coding.

Budget: ~ $200  

I am a savvy IT admin, but don't game much and don't really care to decipher all the GPU jargon.  Any suggestions?  Am I screwed with a 300W PSU and PCI-E 1.1 and is it going to make a huge throttle difference if I buy a 2.0 card?

I would suggest something like a ATI Radeon HD5550/5570 - will do everything you want including the games (even newer ones will play quite well at medium resolutions/settings) and will be within your budget.

Furrthermore, should still be fine with the 300 Watt PSU you have - I did some calculations using the calculator above and it come out at 204 watts minimum and 254 recommended - that included 1 7200 RPM drive, 1 DVD/RW drive and 2 90 mm fans.

HD5570s are around $70.00 - $90.00 so you don't have to spend that much.



the 300 W PS limits your choice really; if you want a better card, i would put in a 500-600 W unit
you can calculate the mpower you need here  :  http://www.extreme.outervision.com/psucalculatorlite.jsp

also, what do you mean with " if I buy a 2.0 card" ?
The 1.1 bus typically only maxes out at very high graphics. Running Modern Warfare in normal resolution and normal/low quality settings will not be a problem with a $200 card in that machine. You don't need to worry about the PCIe 1.1 bus, you have other things that will bottleneck before that like the CPU.

I am a bit worried about the PSU though. If it's a standard size you can just switch it out for $30 and be left with $170 for the graphics card, otherwise you might be a bit screwed...

- "2.0" as in PCI-e 2.0.  Thanks for the PSU calculator.

- I am very comfortable with upgrading the PSU to 500 W, albeit I will have to ensure the box will fit actually fit in a proprietary HP case.  

- I did a bit of search on Newegg and came up with:


So theoretically that would work as long as I get a compatible PSU to go with it? or should I scale down?
That looks like a good choice! Lots of performance per dollar and a nice quiet cooler. I say go for it before the horde of ATI/nVidia fanboys arrives in the thread. :)

If you do upgrade your PSU and your budget is only $200.00, then I'd suggest something like the HD5770 @ $119.00 - plenty to spare for a decent PSU.


You need to consider cooling within your case so don't go for too powerful a card otherwise you'll have heat problems which may require additional cooling fans.

Decided on Radeon HD 5760.  Ultimately on price and not the need to upgrade PSU.  Thank for your all your input!
