My PC has an i7-14700F, RTX 5070 Ti, 32GB of DDR5, and a Gigabyte B760M C V3 motherboard. The 2TB AGI NVMe drive has been hitting 100% active time with extremely high response times, causing downloads and installs to drop to 0 and sometimes making the entire system nearly unusable. I suspect the drive may be defective or simply poor at sustained workloads.
I mainly use the PC for gaming, large Steam and Game Pass downloads, game installs, mods, Windows, and everyday tasks. I want a reliable 2TB PCIe 4.0 M.2 NVMe SSD that can handle those workloads without choking. My target budget is roughly $150–$250, though I could spend more if there is a meaningful reliability or performance advantage.
The Samsung 990 Pro 2TB, including the heatsink version, caught my attention, but I do not want to pay extra for performance I will not notice. Is it a good choice for this system, or would a cheaper drive from a reputable manufacturer perform essentially the same for gaming? Should I prioritize TLC NAND, a motherboard heatsink, or particular warranty and endurance ratings?

The 990 Pro is excellent, but it is probably more than you need for gaming and normal downloads. A good PCIe 4.0 drive from a reputable brand should feel virtually identical in games and everyday use. Look for TLC NAND, a decent controller, a five-year warranty, and reasonable endurance ratings. Kioxia, SK hynix, Crucial, Kingston, Lexar, Seagate, PNY, ADATA, and similar established brands are worth considering. I would avoid unknown bargain drives, especially if the specifications are vague.
Before replacing it, check whether the AGI drive is running out of free space, overheating, or reporting SMART health problems. Also update its firmware and confirm the motherboard is using the proper M.2 slot. A defective or thermally throttling drive can explain the 100% active time and huge response times better than simply choosing a faster model. If the drive checks out, a reputable TLC PCIe 4.0 replacement with the board's heatsink should be enough.
The 990 Pro is a great drive and will work well in that system, but its extra benchmark speed usually will not translate into faster game loading. Buy it if the price is competitive or you specifically want Samsung's software and strong performance. Otherwise, put the savings toward a similarly specified 2TB TLC model with a five-year warranty. The motherboard heatsink should be sufficient, so the heatsink version is not necessary unless your board lacks proper M.2 cooling.
Be realistic about pricing, since 2TB SSD prices can vary a lot. Do not settle for a suspiciously cheap, no-name model just to hit the budget. A reliable 2TB PCIe 4.0 TLC drive is the sensible middle ground; spending 990 Pro money only makes sense if the price difference is small. An HDD would save money but is a poor fit for modern game installs and would not solve the sluggishness you are trying to avoid.

TLC is a worthwhile filter here. QLC drives can still be fine for game storage, but they are more likely to slow down during very large writes once their cache is exhausted.
