Upgradeing to a new video/graphics card?

at the moment i have a nvidia geforce 6150se nforce 430 and it is integrated ramdac. I want to install a new video card XFX HD-477A-YDFC Radeon HD 4770 512MB 128-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card. Can you tell me what the specs are and how good this card will actualy run. Also i need to know how to install one thanks.|||At the moment you have integrated graphics which means you dont have a physical card 'plugged in' the motherboard. installing it is simple, just slide it in to the empty PCI-E slot ASSUMING YOU HAVE ONE!!*** , probably 'upsidedown' so the bit of the videocard with the VGA/DVI connections is facing the back of the computer case. plug the video cable into the graphics card conenctions on the back of the case and and turn on the computer. if you see the computer start up with the black and white writing etc like normal then everything is fine..



the motherboard may detect the card automatically. If you dont see anything then either A) the new card is not inserted properly, and/or B) the computer still thinks the graphics are coming from the old built in graphics. put the video cable into the old video connection and restart and if you can see the computer start up. if you can its B) and you need to press whatever it says you need to press, to enter SETUP (pretty much as soon as you turn on the computer). navigate all the menus (without changing anything) untill you find something probably called Integrated/ onboard graphics or Northbridge [setup]. change it to use PCIE. press F10 i think to save changes and exit. plug in your video cable into your new videocards connection and your computer should start up normally.



You can tell if the graphics card is inserted properly or not because when you tuen the computer on it will most likely spin up the fan for a second. ( a noise you wouldnt have heard before)



*** you may have an AGP slot if your computer is old. your graphics card will not fit in this slot and you will need to hunt down an AGP version of 4670 or 4570 or whichever similar card ATI has done in AGP. if you add the make and model of your motherboard i'll tell you.



also consider your Powersupply may not be up to the task of a new graphics card. if its over 400watts everything is good. if its 250watts or under the whole computer wont work i expect.



the XFX 4770 is a good card so if you get it working it will really boost your graphics performance!



I probably said all this in a really complicated way sorry. Good Luck!
