HP OMEN Obelisk Desktop: i9-9900k, 16GB RAM, 256GB SSD, RTX 2080 Ti Expired

More Budget friendly still good specs.
I7 9700k
8gb ram
256gb nvme
2080 super
$1349

Just keep it as 1tb basic hard drive and buy a 1tb ssd to add on for $80. It'll be cheaper than upgrading to their 256 ssd

Re. 2080TI. Unless you get an EVGA, the brand doesn't matter too much. EVGA stands out just because of their customer service, whereas people have varying experiences with pretty much all other brands. (Of course, some people have had bad CS experiences with EVGA too, but in general they are by far the best.) All brands have very good, and relatively poor cooling solutions, depending on which model you are getting. So really: if you are considering brand, it's pretty much "EVGA or anything else". Then decide whether you want an A-chip (binned, and factory overclocked) or a non A-chip. Performance will typically be 3ish% apart, but no more than 5%. From there on, decide on how much you care about acoustics - in terms of performance, silicon lottery will have a bigger effect that thermals, so don't get too hung up on a few Hz difference because of downclocking. Edit: blower style cards might be the exception to this as they really don't perform well, and will lower your clock rate and performance considerably on the order of 10-15% and are really only sensible under very specific conditions.

All that said, you do not get manufacturer warranty if you buy a pre-built. So if you definitely are going the pre-built route, your main considerations should be A-chip or not, and acoustics. I haven't seen any convincing evidence that one brand has a higher fail rate than others (but if someone has that, please do share), so if I were you, I would not consider brand a factor.
