In the same (upgrade) boat here..my i7 PC is 8 (!) years old and while it 'mostly' runs fine, I'm spending a heck of a lot of time constantly tweaking and cleaning things up to keep it humming..
Been hoping for some good black Friday deals but most retailers have announced what they will have already given the shorter shopping season this year with Thanksgiving being so late..must say I'm a bit underwhelmed by the deals, tho - probably not as aggressive this year since MS turning off updates for Win 7 is going to drive a lot of sales so demand will be up..
I found what looks to be a good website for comparing specs between things like i5, i7, graphics cards, etc. It's from actual user benchmarks and gives good data aggregation and 'net' differences between the different options..here's a link to a comparison between the i7-9700 and i5-9600k, for example..
https://cpu.userbenchmark.com/Compare/Intel-Core-i7-9700-vs-Intel-Core-i5-9600K/m816180vs4031
I was going to go i5 to save a few $$, and while the i5-9600K runs at a higher base clock speed than the i7, I might miss the extra cores of the i7 on demanding apps like Lightroom. Was also going to skip having a discrete GPU, but Lightroom will also probably drive me to get that as well.
Lot more $$ than I was planning or want to spend - looks like about $1,199 (after 'supposedly' $400 off for Black Friday) for a Dell XPS with i7-9700, 16 GB RAM, 250 GB SSD + 1 TB SATA and a dedicated, high-end GPU (NVidia RTX 2060). But it'd be a beast of a box and hopefully last another 5+ years also - hopefully longer.
If anyone has any opinions on i5 vs i7 for demanding apps like Lightroom, would love to hear other perspectives on this..
Also would appreciate any better Black Friday deals anyone has found..I'm trying to stay name vs off-brand, though, as the few $$ I could probably get off-brand in all likelihood may not be worth the likely added aggravation long-term..I plan to have this next box for at least 5+ years..
I also wonder if we're going to see 'better' deals on the day of Black Friday or Cyber Monday..hard to say since BB, Dell, AMZN, etc have all already published their Black Friday deals online and even in flyers..
