I've been playing competitive online games—mostly competitive shooters—for nearly two decades now. And I'm very fortunate in having been able to try a bunch of competitive PC gaming peripherals, monitors, and so on, to figure out what's worth its salt for actually improving my in-game performance.From sifting through various discounts and deals from different retailers during this Amazon Prime Day, I've been able to pick out a few that I'd be happy staking my name to as a recommendation for fellow compet-FPS-ers.We're keeping track of all the Amazon Prime Day PC gaming deals hereAlmost all of these are products I use, or have used, personally. The 400 Hz KTC monitor, for instance, sits in front of me right this minute, and is what I'll be booting up Counter-Strike 2 on later this evening. Ditto those IEMs, which are a wonderful pair of budget drivers that are great at audio imaging to place enemies on the map (just ensure you've got enough motherboard audio juice to power it, or have a DAC—even a cheap one).I've also thrown in something many of you might not consider: aftermarket mouse skates. If yours feel nice and smooth, there might be little point switching. But if you fancy an upgrade, good dot skates like those X-RayPad ones can make for a super quick, easy, and affordable upgrade. Just remember they might take a little wearing in.Amazon Prime Day competitive peripheral and monitor deals X-Ray X-Raypad Jade Speed mouse skates Linsoul Tripowin x 0DiBi Vivaci in-ear modules GK GAMAKAY X Naughshark Ns68 Rapid Trigger Wired Gaming Keyboard SteelSeries Qck L Performance Balance Gaming Mousepad Mchose L7 Ultra+ 48-gram gaming mouse Corsair Sabre V2 Pro 36-gram gaming mouse Alienware AW2525HM 320 Hz gaming monitor KTC KTC 25M1 400 Hz gaming monitor If you're dragging your skates around like a down and out Mickey on Ice, you might prefer to stick a few of these dots on the underside of your mouse instead. Pair these with a slick mousepad and you'll have no excuse.Key specs: 40 dots | Two adhesive remover wipesView DealThese are cheap but you'd be surprised how far a pair of in-ear monitors can go for gaming. They're great for positioning, staying alert, and at this price, saving some cash. These are what I use whenever I play Counter-Strike now (which is, err, probably too much...).Key specs: 10 mm Titanium Dynamic DriverView DealAn 8 KHz polling rate, Hall effect switches, rapid trigger, and nice double-shot PBT keycaps. The Gamakay x NaughShark NS68 is noticeably a cheaper keyboard in feel, but those internals truly are phenomenal. Rapid trigger will be key here for counter-strafing in CS2 or Valorant, for instance.Key specs: Bluetooth, 2.4 GHz and wired | 8 KHz | Hall effect View DealMy colleagues may make fun of me for caring about my mousepad but, believe me, it makes a difference for competitive play. This SteelSeries pad is specially tailored to performance and a balance of speed and control.Key specs: Fabric | Non-slip neoprene baseView DealThe L7 doesn't weight much at 48 grams and yet it packs a great sensor and a decent sized battery. It's a competitive shape, and it makes you wonder, why spend so much more for a speedy FPS mouse when something like this will do just fine? I reviewed the L7 Pro+ model earlier this year if you want to read up more.Key specs: Wireless | 42,000 DPI | 8K pollingView DealThis mouse is incredibly light at just 36 g, and somehow it's achieved this with nary a hole in sight. Apart from this, it's pretty barebones, but a good sensor and low weight is all that's needed for some seriously competitive FPS gameplay, and this mouse delivers on both fronts.Key specs: 33K sensor | wireless | 36 g weight | 70-hr batteryView DealFor competitive FPS gaming on a budget, this is 100% where I'd be spending my money even at retail price, but especially so with this discount. I rated the monitor highly in my review, in part because you're getting a nice refresh rate for the price, but also because it's a pretty nice all-rounder too, with an IPS panel that has some decent HDR. Just note there is some perceptible motion blur, so it's not perfect.Key specs: 25-inch | 1920 x 1080 | 320 Hz | IPS | 0.5 ms (GtG)Price check: Amazon $249.99 | Dell $249.99 | Walmart $249.99View DealI'm looking at this monitor while I write these very words, so the benefits to it are especially fresh in my mind. There's one very big benefit, and that's its whopping 400 Hz refresh rate. The second benefit is getting this refresh rate for a reasonable price. I'm finding it a pleasure to use for competitive FPS gaming in CS2, and it's not too bad for general use, either.Key specs: 24.1-inch | 1920 x 1080 | 400 Hz | TNView Deal
