I want to upgrade my PCs graphics card, but I have no idea what's the max it can handle. I'm running a HP Pavillion 753n..I have a GeForce MX440 64mb..used to have a FX5200 128mb but it burned up. I would like to upgrade to a 256mb now, but I dunno if my comp supports it.
You can easily grab an ATI HD 2400 or 2600 Pro AGP type card that will still run. Even the newest AGP cards are backward compatible if the board there is only 4x/2x and not 8x/4x capable.
I just slapped an MSI GeForce FX5200 128mb on an old Socket A build without problems to see 98SE run there. The support information didn't specify if the board was 8x/4x or only 4x2x however while a new card can still be used as a replacement. Video cards as a rule are more backwards compatible then other hardwares in general. An HD 2400 Pro 256mb DX10 compatible card is seen for $49.99 at http://www.newegg.com/Product/Product.aspx?Item=N82E16814102734 A 6100 was seen for $32.99 as well.
You have the choice between Corsair as well as Kingston since you won't gain from trying to run performance dimms on the old system. 2gb of Kingston ValueRam smoothed things out on the old Socket A build here running XP/98SE at the time. XP was the primary while a tweak of the autoexec.bat file allowed 98 to run well with over 512mb installed.
The supply will probably about a 300-301w model which would allow for a low end to mid range card would still work. Saving for the eventual upgrade into a newer better system would be the thought rather then spending any good amount however on the current model there.
Don't ever ask such a stupid question again (jk). I have that RAM. Well, not completely because i have the DDR2 5300 version and the RAM is great. Make sure it's compatible with your current motherboard setup. The link you've posted up leads to Kingston HyperX DDR 184 pin.
Any high end model even an older one would easily tend to tax the small supply HP tossed in there. You will have to wait until you are in a better system even better yet a custom case once you get to that point to see any real high ending seen there. For now just goin with the basics and saving on the "do re' me" is the smart move.
