I have a HP a250n pentium 4ht 2.60 mhz with 1gb RAM run Windows 7 . I have be think about buy a new pc , but figure it would be WAY cheaper to just upgrade my video card . after search around for agp4x\/8x video card , I find that the hd3850 get the most praise out of the other 512mb card , so I decide to give it a shot . as soon as I take the hd3850 out of the box , I new I be in for something awesome . when I switch out my NVIDIA geforce5200 128mb card to the hd 3850 , the fp on doom 3 sky rocket ... not to mention overall pc performance . also , Fallout 3 and leave 4 dead run a smooth 30fp at 1024x768 . this card give new life to my pc . dual DVI , S-Video , dual monitor support ... but no 1080p . only thing be that you have to get a 450w or greater power supply with 30amp on 12 volt with 2x4 power connector recommend . if you be look into get one of these , you might want to do some research before it arrive at you doorstep , so that you have everything you need to install it and have it up and run in no time without any issue .
