rtx2070 is right in your budget and has ray tracing cores. You could go with the gtx 1080 for a little more, but according to https://gpu.userbenchmark.com/Compare/Nvidia-RTX-2070-vs-Nvidia-GTX-1080/4029vs3603 the rtx 2070 seems like a direct upgrade. The RTX 2070 is also a much more recent release.

id get a 2060

I heard some guy say this was the best value I forget who though.

before you can make a reasonable decision you need to evaluate whether or not a gpu upgrade will bottleneck your pc

what cpu do you have

sorry for not including this but I have a i7-7700

you should get a new cpu then imo, i have a 1060 6gb and it pretty much bottlenecks my 7700k in all triple a games i play
edit: unless u dont play triple a games/care enough since it isnt the end of the world uh haha

maybe of the rtx cards but the 1660ti is “best for value.”

its also the only one that doesnt produce a sizable bottleneck between the 1080, 2070, and 2060.

i would go with the 1660ti until you can afford to upgrade your cpu as well.

also yerb that cpu is not bottlenecking your gpu. your gpu isnt powerful enough for a 7700k

Ray Tracing is a meme and you should not buy an RTX card with the expectation of being able to do meme tracing at a acceptable frame rate even a year from now.

Get one of the lower budget AIB RX 5700 XTs. They sit between the 2080 and 2060 super depending on the game and sell for 2060 super prices.

The Sapphire Pulse or the Powercolor Red Dragon XT RX 5700 XT looks like the best value new cards on the market right now. The Gigabyte one is also supposedly decent. Avoid Asus and XFX.
If you are willing to go used and do some tweaking Vega 56 can be found on ebay for only $200. Many of the reference cards can take a Vega 64 bios and with a conservative mem OC/undervolt you are looking at 2060 super tier performance.

ray tracing is a meme tho.

That would depend on the settings used and the game. Having a bottleneck isnt that big of a deal. Just gives you a clear upgrade path for your next part.
Personally i would go the Ryzen 5 3600/ Vega 56 route. Should be able to squeeze that into the budget.

You do realize Pascal is falling off a cliff in new games right?
Depending on the game it's literally RX 580 tier. That why i've been recommending used Vega over pascal.

I'm seeing a few mixed answers so I want to also add that the main games I play are TF2, CSGO, Dead By Daylight, Fortnite, and Apex Legends. I am solid on tf2, semi okay on cs, good on dead by daylight, but the other games can be pretty hard

You still haven't said what's your PSU

All of those games are old enough or low enough spec that it doesn't really matter what card in this tier you get.

The other can games can be pretty hard as in hard to get the framerates you want?

How many fps are you getting and how many would you like? That should give you an idea of how much of an upgrade you need.
Price to performance ratio generally only gets worse above ~200$ so it's better to get a GPU that does what you want and not much more and then upgrade again in a couple of years.

Do you run high refresh rate/high res? Based on meeting your budget I'd go for the 5700xt or 5700. The 2060 super and 2060 are also decent choices but they trade price for Nvidia's proprietary features which is questionable at the budget level. If you want to save some money you can look at the 1660 super/1660ti (whichever is cheaper, they perform similarly). For used options as I believe was said before you can pick up a Vega 56 for around 250, then overclock it and/or flash a Vega64 vbios and/or mess with powerplay modding and get some nice performance.

Keep in mind that even a 1660 is over twice as powerful as your card. At the 350 to 400 dollar price point, the cards are at least triple as powerful. Just depends on how much FPS you need at which resolution.
