I'm planning a PC with a budget of around ₹75,000 (roughly $700–750). My main uses are gaming, AI/ML experimentation with CUDA models, and general office work. I'd prefer an Nvidia graphics card and want to prioritize VRAM, ideally something around an RTX 3050 or better if possible. Is 8GB of system RAM still acceptable, or should I start with 16GB? Would DDR4 be sufficient for this budget, or is DDR5 worth choosing? I only need a basic 500GB SSD rather than an especially fast or large drive. I'm considering an AMD processor for a better future upgrade path and would like to keep the motherboard around ₹13,000–14,000.

Don’t build with only 8GB of system memory. Start with 16GB, preferably as two 8GB sticks for dual-channel performance, and upgrade to 32GB later if your AI tools or games need it. DDR4 is completely fine if it lets you afford a stronger Nvidia GPU; DDR5 is mainly worthwhile when the total platform cost is close to DDR4.
If you want the upgrade path, an AM5 build with a Ryzen 5 7500F or similar processor and DDR5 is the more modern option, but fitting that platform and a high-VRAM Nvidia card into ₹75,000 may be difficult. AM4 with a Ryzen 5 5600 is still a sensible budget choice. Avoid overspending on the motherboard—put that money toward the GPU, RAM, and a reliable power supply.
For gaming and CUDA work, prioritize the graphics card first. Try to fit an RTX 3060 12GB or RTX 4060 8GB depending on local pricing, although the 3060’s extra VRAM can be more useful for AI models. Pair it with a Ryzen 5 5600, 16GB RAM, a 500GB NVMe SSD, and a decent 550W power supply. That will usually offer better value than spending heavily on the newest platform.
The 3060 12GB is often the safer choice for entry-level AI because 8GB can become restrictive quickly, even though the 4060 is newer and more power efficient.
Also check the motherboard’s memory slots, BIOS support, and upgrade options before buying. A cheap board is fine, but an unreliable power supply is not—choose a reputable 550W or 650W model.
