I'm planning a PC mainly for gaming, AI/ML models, and general office use, with a total budget of around ₹75,000 (roughly $700–750). I'd prefer an NVIDIA graphics card because VRAM and CUDA support are important, ideally something around or above the RTX 3050 performance level. I'm considering an AMD processor for a better upgrade path and would like to keep the motherboard near ₹13,000–14,000. I only need a basic 500GB SSD, so it doesn't have to be especially fast. Should I start with 8GB of RAM or go straight to 16GB, and is DDR4 still reasonable or should I choose DDR5?

If you want a longer upgrade path, AM5 with DDR5 is the cleaner choice, but fitting it into ₹75,000 while also buying an NVIDIA card can force compromises. You could begin with a Ryzen 5 7500F or similar, 16GB DDR5, and a basic B650 motherboard, then upgrade the memory and graphics card later. However, if the immediate goal is the best performance under budget, AM4 plus 16GB DDR4 usually gives better value. Avoid building around 8GB, and check the final GPU price carefully—an RTX 3060 12GB or another card with at least 8GB VRAM is preferable for AI workloads over a faster card with very little VRAM.
For gaming and AI work, prioritize the NVIDIA GPU and 16GB of RAM before spending extra on DDR5. Eight gigabytes will be restrictive, especially once you run a game, development tools, or an ML environment together. A Ryzen 5 processor on a reasonably priced AM4 board with 16GB DDR4 can leave more of the budget for a card such as an RTX 3060 12GB if you find a good deal. The extra VRAM is much more useful for CUDA and local models than moving to an entry-level DDR5 platform. A 500GB NVMe or SATA SSD is fine to start, although you may want another drive later.
That makes sense. I’d rather have more VRAM than a newer platform if the main workloads are CUDA and gaming.
Also remember that system RAM and GPU VRAM are different. Adding more normal RAM won’t make a model fit into a graphics card with insufficient VRAM.
