apu vs gpu

[PyroStar]

I Have a AMD a4 - 3300 with Radeon HD graphics and I have an ATI Radeon HD 2400 XT since apus have integrated graphical processors how do they perform with graphics cards my computer seems to be very slow and its specs don't seem horrible. The APU is a dual core that clocks in at 2.5 gigahertz and the computer has two gigabytes of RAM I can increase the RAM but the processor still running at 30 to 60% load on Idol. I wonder if I use the onboard graphics if that will improve the computer's performance as opposed to using the graphics card. My next question is how do you utilize the graphics do they have to be tapped into? activated through BIOS? are they automatic? where do they simply just work in tandem with the graphics card weather be on board or Inserted?

Hate to be the one to burst your bubble but an a4 and 2 gb of ram is pretty terrible.

First of all any windows 7/8 computer is going to be slow with 2gb of ram, does not matter if is the newest octa-core skylake i7.

Secondly the a4 is literally the lowest end desktop CPU out there, lower then a Celeron.

To use the dedicated gaphics you just tell the bios to use PCIG (PCI E Graphics).

Your A4 integrated graphics is better then the HD 2400 so just use what the cpu comes with.

To better understand why you need more RAM it's helpful to understand the relationship between the RAM and the CPU..

While the onboard video would typically be better in your case with 2 gigs of ram your better off sticking with the gpu since the onboard video would use more of the system memory
