Last time I upgraded was back in December upgrading to an RTX 2070 and I haven't had any issues with it, the only thing that could cause some crazy things is the 2 ram dims of 4Gb I added, they where cheap 1333Mhz 4Gb each, while I have 2 other corsair dims of 4Gb with higher clock speeds, however I downklocked my original corsair dims to 1333Mhz to match the new kingston dims I have and I haven't ran into any issue.I cannot upgrade my ram dims because, my i7 4790K is one of the last CPU's to use DDR3 ram, DDR3 ram is not being made anymore and the stock is very low cauzing prices to be very high, especially for higher clockspeed models.And the i7 4790K while being 'old' at this point was a crazy beast at it's time, and it's still plently powerfull for 60FPS/1080P gaming.I realise that GW2 uses a different engine then most other games I play, however I have no issues with any games I played.Some examples include:Tom Clancy's The Division 1Tom Clancy's The Division 2Sekiro: Shadows Die Twice,Resident Evil 2 remakeRage 2Far Cry 5Final Fantasy XV All of these games at 1080p (Well 1200P in my case since I got widescreen FHD) / 60FPS at nearly ultra settings in all games.Even Final Fantasy XV which is probably the highest powerhungry game I have I have all but (Hairworks and another gameworks feature I don't really recall now turned off) turned on & at ultra settings and I almost never get a stutter or anything, average of 60FPS. And some other MMO's I play are Guild Wars 1, Final Fantasy XIV, (also tested on ESO, WoW & SW:ToR) and no poor performance there, all 60 fps with ultra settings In the 6Months of I have this GPU now I never had a blue screen, crash or game crash, freeze or anything else. So I tried it again by removing Drivers and doing clean install of driver, reinstalling GW2 as adding -repair in the target field didn't do anything.I ran a CPU stress test on all 8 threads & a GPU stress test at the same time for +8 hours before I left to work, when I came back home the PC was still running fine (65C degrees max) and still running.I also did a memtest with *4 passes and all my ram dims are working fine too. I'll contact Anet support & will also search around the internet for tweaks and such like I did back in 2012 to have it on acceptable performance/stabilisation. Sorry for the slow answers, I work full time and don't always have much time to check back here before I drop into bed.Thanks for the advice so far.
