Hey everyone! I'm diving into building my first PC and could use your insights on choosing the right GPU. I'm getting into AI, particularly with large language models and Stable Diffusion, but gaming remains my primary focus, especially wanting to maintain the console-level 4K experience I enjoy with my PS5. Currently, I'm working with a Mac setup that includes an M2 Max Mac Studio and an M3 Pro MacBook Pro, but they fall short for tasks like Stable Diffusion. I'm definitely making the switch to Windows. Here's where I'm getting stuck: I've heard great things about the RTX 3090 for AI due to its 24GB VRAM, but I also read it's not the best for 4K gaming and performs better at 1440p. I'm considering the higher-end RTX 4090 or 5090 for better 4K performance, but the steep prices (ranging from $2,000 to $4,000) have me hesitant. I even thought about running two 3090s for AI purposes, but I'm unsure how much that would benefit gaming. I really want a GPU that can handle gaming at 4K like my PS5, perform well with Stable Diffusion and LLMs, and not completely break the bank. I've looked into the 4070 and 4080, but I'm worried about the lower VRAM. What do you all think? Is the dual 3090 setup worthwhile, or is the 4090 the better long-term choice? Thanks a lot for any advice—and I appreciate input from anyone who balances AI and gaming!

Honestly, if you're looking for value, the RTX 3090 is hard to beat for your needs. Sure, the newer models like the 4090 are tempting for 4K, but they’re way overpriced right now. I'd focus on getting the 3090 for now, and if you want to experiment, you could always consider picking up a second one later when the prices drop. Dual GPUs might not be as beneficial for gaming, but it could help with AI tasks.
It sounds like you're leaning towards the RTX 3090, and honestly, it’s still a great option for both AI workloads and gaming, despite some limitations at 4K. Remember, modern titles on consoles often don't run true 4K anyway, thanks to upscaling. The 3090 has solid performance for LLMs and is still pretty powerful for gaming. Just don’t expect it to outperform the latest cards at 4K.
Thanks for clarifying the 4K performance! I was worried I’d be stuck at lower resolutions if I went with the 3090. Might just have to recalibrate my expectations based on that!
That makes sense! I think I'll start with the single 3090, and if I find I really need more power later, I'll explore the dual setup down the line.
