hello everyone hope you all doing great

I coming back to boxing I use to box on this computer

Q6600 2.4Ghz 8gigs of memory GTX 280 1gig memory

i thinking of upgrading this to a TI 560 with 2 gig memory

my current setup works good for 4 boxing but when i go 5 i get a bit of lag sometimes

or do i need to do a cpu/motherboard upgrade like the I7 2600k

however would my current card work well for that

thank you all for the help
cheers
