New Build - GPU performance on the overall system question

[Alakagom]

Hi,

Not sure this is the right thread, but here goes anyway. Pretty noob-ish question so forgive.

I'm looking to build myself new computer, I am not a gamer really so I'm building my pc purely for speed in tasks like excel/data crunching/databases etc.

My current GPU is Radeon 5700 From what I saw the 6700k has the Intel HD530 which what I saw in passmark is actually more powerful than 5700 which is cool

So to my question as per title, does discrete GPU going to have any affect on speed of my overall system? I assume it'll have some anyway, but is it big or very minute? I'd rather save myself money for now and maybe buy a discrete when Pascal comes out in future.

Thanks in advance.

If all you have is a 5700 I would definitely just run the 6700K's iGPU.
If you're not a gamer there's no real use to buy a dedicated GPU unless you have a rendering software that'll utilize one.
