Between dell precision 7710 and 7720

[oliveria]

Hello good people, I want to purchase a workstation in ebay and I have two options that are a bit tricky to chose so help me kindly, there's a dell precision 7710 with Xeon E3-1535 v5 and 32GB ram plus 1TB ssd plus quadro M5000M, then we have the dell precision 7720 with intel core i7 6820hq with 8gb ram plus 256gb ssd and quadro P4000

I'm abit faclscinated with the quadro P4000 in the dell 7720 which is a better graphics card than M5000M, this is what makes m hesitant to pick precision 7710, whats your opinion, thanks in advance

Really depends on what you need, do you need the extra RAM and space? Is there a price difference that matters to you? Can you upgrade the 7720 to what you need without cost issues?

The precision 7710 cost $460 and the precidion 7720 cost $400, its possible to upgrade the precision 7720 though at a high cost, getting a good graphics card with other low specs will make me spend more money , but the graphics card of P4000 is good for me more than the M5000M, at the same time I really like Xeon V5 processor in precision 7710, the question is, is the Xeon all that lightning fast that it makes the i7 6820hq in precison 7720 not worth considering, or are the speeds not that far from each other

There is just under a 10% speed difference between the CPU but the Quadro P4000 on it's own is selling for around $200 on eBay. They are actually pretty equal in value, just one puts it on the video card and the other on the CPU and RAM and drive.
