How exactly do i go about installing a new video card?

i would really like to install an nvidia geforce 8800, but i have no idea what other components i would need to install with it....



do i need more RAM?

do i need a better power supply?

im slightly confused....



and this is my computers specs (but with a geforce 6150 card instead):

http://www.bestbuy.com/site/olspage.jsp?…|||The minimum requirement for nvidia 8800GTS (the slowest of the 8800) is 400W and the higher end model has higher power requirement. Normally the manufacturer use 250 to 300 W power supply in the system with built-in VGA like yours.



So you definitely need a new atleast 400W power supply... i will recommend that you buy a power supply of 400 - 500 W... not too high and neither too low... Its best that your system runs from 70 - 80% of the wattage of the power supply.



Secondly while buying the power supply do see that if it has requirement 6-pin or 4-pin extra VGA connector... different manufacturer put different socket for extra power on the VGA card, although mostly they do provide convertors but its good if the power supply has the required connector built-in for the extra power of VGA.



Increasing the RAM will help the system performance greatly but it is not a requirement. more of a high recommendation.|||You may need a better power supply if the one you have can't support.

I couldn't see the power supply on the spec sheet so can't tell if you would.|||You will need to buy new power supply (with PCI-E connectros,to add power to your new Geforce 8800). RAM you don't need as you have enought(but if you liek to play games add one more 1GB PC2-4200 DDR2). Good luck! But baiscally uou just need new power supply and thats it :-) Then just buy new card,and plug it in in PCI-Ex 16 slot(th elongest one under processor slot). Then start up and then don't foget to sdisable integrated card in bios after all. Best regards! Enjoy!|||Isn't a Geforce 6150 just integrated graphics processing built into the motherboard ?



I imagine you would need a better power supply; it doesn't say what the power supply is for but for a dual core 1.8 Ghz processor I doubt it would be any more than a 450... thats not enough for an 8800...



Incidentally an 8800 would cost more than that entire computer...|||U don't need other components needed to install geforce 8800 unless ur powersupply is less than 300W. I think since its an 1.8Mhz processor with a geforce 6150 card, u will need to buy anew powersupply. See what rating mentioned on your power supply & ask dealer what power 8800 needs. But on safe side if u bought a new 500W powersupply will solve all problems.
