[Q] Second GPU to boost performance?

[USA-RedDragon]

Ok, so this may be a stupid question, but I'm new to the hardware-side of computers.

I have a dual-xeon gaming board, and it has an integrated ATI ES1000 gpu. I also have a GTX 750 TI and Radeon R5 220. 

Now, for obvious reasons, the GTX 750 TI is my daily-use card. My motherboard also doesn't support turning off internal gpu. So in windows when running heaven benchmark, I disabled the driver for the internal gpu in Device Manager to help bring the score down to a fair level. With it on, my score was in the 700s, whereas with it disabled, I got in the 500s. Was this just my 4 am mind seeing things, or did the internal gpu help the performance in the benchmark, and if it did, can I use my Radeon R5 220(yes, a cheap card, ik) as well, causing a marginal increase in games and benchmarks? 

 

Thanks for the help,

Jacob

As of now, I don't think you can. The cards are from Nvidia and AMD.

You might want to do a little research on SLI and Crossfire to see how these things work (I don't know much).

SLI and Crossfire are to GPUs what RAID is to drives iirc. I mean just having the drivers installed and gpus running

Short answer : Yes Long answer : Yes the card you are using as a main card is lots better than the 220, but you probably not see a very huge difference when using the 220 to accelerate your benchmark you may see slight improvements. The only thing to really tell (As not many other Users will be using a 750 ti, an r5 220 and mobo igpu with dual Xeons.) Back on topic, the only way to tell is to try it if you don't see a benefit just turn off the 220.

Your cannot CrossFire/SLI cards from two different manufacturers. But with that said I am curious as to how you could get a better score with the onboard graphics enabled.. blows my mind. But I do know with AMD you can somehow CrossFire your onboard ghraphics (APU) with a dedicated GPU (I think), Defiantly NOT with an NVidia GPU ,but your best bet is to just stick to your 750Ti and do whatever makes it perform better, even if it makes no sense at all.

 

Generally you can only run cards in CrossFire/SLI if they have the same chip (980/970/960), but with crossfire theres more flexibility.
