Graphics card and power supply help!

[TheGreekGuru]

I usually play games like Call of Duty, Battlefield, Grand Theft Auto, Minecraft ,etc. I want to be able to play games on at least 720p resolution and have no lag and I don't want to spend over $200 on a graphics card. $220 max. Any suggestions on which card to get? Also my PC only has a 300watt power supply so I need at least a 500watt to run a graphics card. Will an Antec EarthWatts EA750 750W power supply work with my PC? (I'm not the best with pc internals. This is my first time really installing and swapping out parts in a pc) And any suggestions on GPU's would be great.

MY PC is a HP Pavilion p7-1415. Here are the PC SPECS: http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&taskId=120&prodSeriesId=5295962&prodTypeId=12454&objectID=c03531731

AGAIN ANY HELP WOULD BE GREATLY APPRECIATED!!!!!!

get a 7770 (note: not sure how much this is right now)
a 7870 would be better (by a significant margin). if you can find a 6870 it is also good (and cheap nowadays)

yes a good 750w is plenty

Will the 7870 or 7770 gpu and the power supply work with my PC?

Hi TheGreekGuru,

Yesterday i just bought a new GPU.. I choose ASUS HD 7770 Direct CU Top ( Overclocked ) version for gaming.. you can use standard pcu that got 470watt above and big fan and got 6pin pci cable.

it will be ok...

I was also looking at the Nvidia GeForce GTX 660. How does this card compare to the amd Radeon 7870? is the 7870 better?

 

[swifty_morgan]

so you're going off the budget? how much is it now?

I'd highly suggest spending an extra $10 and getting this card from EVGA GTX 660. Will last for a good amount of time and will max BF3 at 720p very well!

Your power supply should suffice a GTX 660 since it has enough wattage and 2PCI-e connectors.
