((((Is it smart to slap a new GPU on my aging PC build?

**Main Question:**
Which one is more realistic? Maximizing my current mobo and build?
Or just focusing on saving budget for an entirely new PC build?
I want to make sure I'm not wasting my budget.

**My aim:**
- (work) Making my PC better as a 3D Blender workstation for local render and viewport performance for work projects (3D Motion graphic, Rendering, Design)
- (work/hobby) Improving / faster performance on Stable Diffusion for generations and workflow size capability
- (hobby) 4K Gaming on med-high settings on recent games, something like Helldivers 2
- (budget) Realistically maximizing what spec I have now or decide if upgrade not worth it and resort to expensive new PC build, which I think I can't afford right now
- Preference wise, still liking Ryzen + RTX combo

**My current setup:**
- Current PC works great for most things
- Workstation wise it does run on the medium-slow side
- 4K gaming in modest games in modest settings (low to mid)
- Plays okay on games from 5-8 years ago
- 3DS Max and Blender runs okay but performance is limiting sometimes, usually resorted to 3rd party renderfarms for final render
- Stable diffusion and local AI generation in is kinda slow but workable for most basic SD 1.5 workflows

**My current PC Spec:**
- 2 Monitors: One 4K main monitor and secondary HD monitor
- OS: Windows 10 Pro 64-bit
- Mobo: Asrock B450M Steel Legend (AM4)
- CPU: AMD Ryzen 7 3700X
- RAM: 64GB DDR4 3000Mhz
- GPU: Zotac RTX 2070 Super (8GB VRAM)
- Disk #1 System): Samsung 970 EVO Plus 1TB (M.2 NVME)
- Disk #2 Projects): Adata SX8200PNP 2TB (Slower NVME)
- Disk #3 Cache/Misc): an old 480GB Corsair Neutron GTX
- Disk #4 Storage): 8TB Seagate HDD
- Power Supply: Silverstone 1000W Gold (This part is quite old)
- Power Backup: APC UPS 1100W (Just to avoid sudden power blackouts)

What I think are the options (Local SEA pricing):
- Upgrade CPU to Ryzen 5700X3D ($250 USD)
- Upgrade CPU to Ryzen 5800X3D ($360 USD, the max CPU for this AM4 mobo)
- Upgrade GPU to RTX 3090 24GB VRAM ($950-1700 USD, older but with big VRAM)
- Upgrade GPU to RTX 4080 16GB VRAM ($1050-1300 USD, newer but less VRAM)
- Upgrade GPU to RTX 4090 24GB VRAM ($1950-2400 USD, newer but expensive)
- Completely New AM5 based build (which I can't afford right now)

So, what do you guys think? Did I completely miss an option? or do you guys have any recommendation on what I can do?

**Update:**
Added 5700X3D as recommended
