Upgrading from Radeon 5770 but worried about bottlenecking

So my AMD Radeon HD 5770 really isnt't cutting it anymore for gaming, and I'd like to upgrade from it. I'm on a budget, I'd prefer to only spend between $150 and $250 on a new card, as long as it's a significant improvement over the old one. However, I'm curious if you guys think the other components on my 5 year-old rig would just hold a new graphics card back.

Full specs:
CPU: Intel Core i5 750 quad 2.67 GHz
GPU: AMD Raedon HD 5770 1GB
RAM: 8GB
PSU: 450W
OS: Windows 7 64-bit
PCIe Slots: 1
Monitor Resolution: 1920x1080
Country: USA

So... how much better of a GPU could I get without bottlenecking? I don't want to get a whole new PC as mine is running great, but it's just fallen behind in gaming.

For those curious, some games I own that don't run that well: The Witcher 2, Far Cry 3, Metro Last Light, Dark Souls, Bioshock Infinite. I tend to get 25 - 35 fps at medium settings.

There's not much wrong with OUR i5s. ;)
GTX760 or R9 280 will do very nicely, they're similar in price and performance, just bear in mind both need more power than your existing PSU can provide, you'll need to budget for 500-600Watts from a good maker like Antec, Corsair, Silverstone, Seasonic XFX (Pro series) FSP (Aurium series) or Rosewill (Capstone series).
If you're feeing a little adventurous consider adding a better CPU cooler into the mix and dabbling in overclocking, these Lynnfields can overclock to good effect, particularly in the more CPU heavy games out there. If you think you may overclock, raise the PSU to 600 Watts.
