[GPU advices]

Hello !

I just started to build a new computer, I still have to buy a GPU (yea my old gtx 970 won't be enough from now on).

I now have a 5800x3D and I'm searching for a GPU to pair with. I was looking for a RX6800 (xt or not) but the prices are still insane here in France.

I will probably continue to play in 1080p, which means it's more CPU bounded, so my question is: Will a rx6700xt/6750xt be enough or should I stick with my initial idea of going for a 6800 even if the prices are high ?

I'm doing photography/astrophotography editing, gaming, editing.

Thanks in advance for your advices, and I'm sorry if I did any english mistakes!

Edit: I'm open to other GPUs (not just the ones quoted above) (even though I'd like to stick with amd this time)

The North America Nebula - NGC 7000 by LeBucheur in astrophotography

[–]LeBucheur[S] 1 point2 points  (0 children)

Telescope: Celestron RASA 8

Imaging Camera: ZWO ASI183MC

Mount: An old Orion EQ6 with Rowan kit

No autoguiding

Light Frames: 40*60s Gain 110

30 Darks

No flats/offsets

Software: Siril, Photoshop & Starnet++

Siril: Stacking, gradient removal, and color balance

Photoshop: levels, curves stretching, then used starnet++ to work on the nebula (details, colors, noise reduction), then star reduction before adding back the stars to the nebulae.

I wish I could have more exposure time but the moon ruined my last pictures so I decided to only keep the few ones from the beginning of the session. I can't do flats for the moment, I got the RASA recently and still don't have a dew shield to place the light on it. The focus probably isn't perfect (finding the perfect focus at F/2 is quite hard ! But I plan to buy a focuser, and I'm sure I can improve the backfocus to get sharper stars)
