Hi DOYLE,
I do not believe there is a way to upgrade dedicated Video RAM.
But i believe the RAM from an integrated card when adding a dedicated slot card will use that RAM also, if i am not wrong, others can quote me on this.
This is an integrated video card on the system correct ?
You have the PCIe slot to fit this card i believe will work on your system. Only thing is the card is PCIe 3.0, some cards are backwards compatible with PCIe 2.0 systems which i feel your system might be PCIe 2.0.
It's a decent card with 256bit, should be able to play most games these days, but not all.
This one is a step up though http://www.newegg.co...0140722021057:s
Matters by your budget.
One thing that was not listed in your system specs, that was important is this Video card requires a 500W Power supply.
Games today are getting more demanding, a lot of factors to look at.
Also mattering to how much gaming you will do. RAM on system is one, higher the better, CPU speed is another and the speed (MHZ) and the bit rate of card along with it's dedicated RAM.
Even the Hard Drive too, especially needing space for game to install and run fast..
