Advice on HP Nvidia Tesla K40 GPUs

[datacomplex]

@epixoip and @Chick3nman, I will go ahead and return them. I got them for $105 a piece or $420 for all 4, flat rate. Other options were the K10 and GRID M40 also for very cheap.

So to understand clearly, am I better served by grabbing two RTX 2080s? And if so, which edition would you recommend as I see many of them by many different manufacturers. Or should I go for a few of those GTX 1650s? I'm open to recommendations.

Thanks for your input guys!
