Diagnose
Find out what's actually limiting your frame rate, and what a good frame rate is.
How to check for a CPU or GPU bottleneckSet up MSI Afterburner and RTSS, read GPU usage and frame times, and confirm the result with a 30-second resolution test.CPU bottleneck vs GPU bottleneck: which is worse?Why a CPU bottleneck feels worse at the same average FPS, when a GPU bottleneck is the real problem, and which part to upgrade first.Does resolution affect bottleneck? 1080p vs 1440p vs 4KWhy a higher resolution moves the bottleneck from CPU to GPU, what switching from 1080p to 1440p really costs, and when 4K still needs a fast CPU.What is a good FPS for gaming? 30, 60, 144 and 240 explainedFrame times for every common target, what 60, 144 and 240 FPS are each good for, refresh rate and VRR, and why 1% lows matter more than averages.
Fix and tune
Get more FPS from the parts you already have before you spend anything.
How to increase FPS: the settings and fixes that actually workWhich settings raise FPS and by how much, why they help GPU-bound PCs but not CPU-bound ones, the Windows basics that matter and the tweaks that don't.How to fix a CPU bottleneckFree settings changes first, then RAM, XMP and Windows fixes, then the drop-in CPU upgrade that gives the most FPS per dollar.DLSS vs FSR vs XeSS: upscaling, frame generation and CPU bottlenecksWhat each upscaling preset is worth, which GPUs support DLSS, FSR 4 and XeSS, how frame generation affects latency, and why none of it fixes a CPU bottleneck.
Memory and VRAM
How much RAM and video memory games need, and when speed matters.
How much RAM do you need for gaming? 16 vs 32 vs 64 GB in 2026FPS and 1% lows with 8, 16, 32 and 64 GB in four builds, why the answer depends on whether you're CPU-bound, and who actually needs 64 GB.Does RAM speed matter for gaming? XMP, EXPO and dual channel explainedWhen faster memory raises FPS and when it can't, how to turn on XMP or EXPO, why two sticks beat one, and the sweet-spot kits for AM4, AM5 and Intel.Is 8 GB of VRAM enough in 2026? What runs out first, and when to buy 16 GBHow much video memory games need at 1080p, 1440p and 4K, what running short costs, and the 8 GB vs 16 GB versions of the same card side by side.
Upgrade your CPU
The best drop-in upgrade for each socket, and whether the newest chip is worth it.
Best AM4 CPU upgrade in 2026Ryzen 7 5700X3D, 5800X3D or Ryzen 5 5600? FPS and bottleneck tables against today's graphics cards, plus BIOS and cooler checks.Best LGA1700 CPU upgrade for 12th to 14th gen Intel PCsFrom an i3-12100F, i5-12400F, 12600K or 13400F to a 14400F, 14600K or 14700K: gains, the stability BIOS to flash first, and when AM5 is better.Best AM5 CPU for gaming in 2026Ryzen 5 7600, 9600X, 7800X3D or 9800X3D? FPS and bottleneck against RTX 5070 to 5090, picks by graphics card, plus BIOS and EXPO setup.Ryzen 7 9800X3D vs 7800X3D: is the upgrade worth it?FPS and 1% lows for both chips with an RTX 5070 Ti, 5080 and 5090 at 1080p, 1440p and 4K, game by game, and when swapping actually pays off.
Pair a CPU with your GPU
Which processor keeps each graphics card fully busy at 1080p, 1440p and 4K.
Best CPU for the RTX 5060 and RTX 4060What counts as enough CPU for a budget graphics card at 1080p, FPS for eight processors, and when the cheaper chip is the smarter buy.Best CPU for the RTX 5070 and RTX 5070 TiFPS and bottleneck for 11 CPUs with each card at 1080p, 1440p and 4K, plus the best pick for every budget and platform.Best CPU for the RX 9070 XT and RX 9070FPS and bottleneck for 10 CPUs with each Radeon card at 1080p, 1440p and 4K, plus FSR 4, Smart Access Memory and the AM4 option.Best CPU for the RTX 5090 and RTX 5080FPS and bottleneck for 12 CPUs with each card at 1080p, 1440p and 4K, how DLSS shifts the load to the CPU, and picks for AM5, Intel and AM4.Is the Ryzen 7 7800X3D good with the RTX 5070 Ti?The verdict at 1080p, 1440p and 4K, FPS by game type, how it compares to the 9800X3D and 7600, and whether it can drive an RTX 5080 or 5090 later.
Plan a build
Match the processor and graphics card to each other, to your monitor and to your budget.
How to plan a balanced gaming PC buildMatch the CPU and GPU to your monitor, split the budget sensibly, and avoid the pairing mistakes that waste money. Includes a tier table for 1080p, 1440p and 4K.Budget gaming PC build: a $700 part list with FPS and bottleneck numbersA concrete part list for a 1080p gaming PC around $700, four CPU and graphics card options compared, and how to upgrade it later.1440p gaming PC build: a $1,200 part list with FPS and bottleneck numbersA concrete part list for a 1440p gaming PC around $1,200, five CPU and graphics card options compared, when an X3D chip is worth it, and the upgrade path.Gaming laptop bottlenecks: TGP, thermals and CPU vs GPU limitsLaptop vs desktop GPUs, TGP, HX vs H vs U processors and FPS for common pairings, plus the MUX, power and cooling settings that matter.Mac vs gaming PC: what the same money buys for gamingMac mini, MacBook and Mac Studio against PC builds and gaming laptops at similar prices: FPS, which games run, unified memory and who should buy which.
