Quick Answer
The RTX 4070 Ti at R14,000 delivers roughly 50–60% more fps at 1440p over the RTX 3070 Ti, and 30–40% over the RTX 3080. If you're on an RTX 3070 Ti (R4,500 used), the gap is meaningful but the cost is steep — only upgrade if you're targeting 4K or high-refresh 1440p. RTX 3080 owners are better served waiting for RTX 50 series pricing to mature.

The RTX 4070 Ti has 12GB VRAM vs the 3070 Ti's 8GB and 3080's 10GB — a practical advantage for high-fidelity 1440p and entry-level 4K.
DLSS 3 vs DLSS 2: The Generation Gap
The RTX 4070 Ti supports DLSS 3 with Frame Generation (FG), which is exclusive to RTX 40 series. RTX 3080 and 3070 Ti support DLSS 2 (AI upscaling only, no FG). In Alan Wake 2 at 1440p Ultra with DLSS Quality + FG, the RTX 4070 Ti hits ~145fps vs the RTX 3080's ~95fps with DLSS 2 Quality — a 53% gap that DLSS 3 amplifies beyond raw rasterization differences.
Should You Upgrade from RTX 3080 to RTX 4070 Ti?
If you're on an RTX 3080 and targeting 1440p gaming, the upgrade is hard to justify — you're looking at 21–27% native fps gains for R14,000. If you're targeting 4K at 60+ fps natively or want DLSS 3 FG support, the 4070 Ti makes more sense. Otherwise, consider the RTX 5070 Ti (~R20,000) for a larger generational leap.
FAQ
Is the RTX 4070 Ti good for 4K gaming?
Yes — at 4K High settings, the RTX 4070 Ti averages 60–75fps in demanding titles and 80+ fps in less intensive games. With DLSS 3 Quality enabled, 4K gaming at 90–120fps is achievable in well-optimized titles. For consistent native 4K at 100fps, step up to the RTX 4080 Super.
What's the difference between the RTX 4070 Ti and RTX 4070 Ti Super?
The RTX 4070 Ti Super (~R18,000) adds 16GB VRAM (vs 12GB) and about 10–15% more fps. The 16GB VRAM is meaningful for 4K gaming and future-proofing. If your budget extends there, the Super variant is the better long-term buy.
What PSU do I need for the RTX 4070 Ti?
The RTX 4070 Ti draws 285W TDP. Pair with an 800W 80+ Gold PSU minimum. A Corsair RM850x or Seasonic Focus GX-850 (~R3,200–R3,500) is ideal. The card uses a 16-pin (600W) connector — use Nvidia's provided adapter if your PSU has 8-pin connectors.
from an RTX 3080 to RTX 4070 Ti, resell the 3080 first — SA second-hand market prices for RTX 3080 10GB are still R4,000–R5,500, which meaningfully offsets the upgrade cost of ~R14,000.
