im clueless, is this ok?

I just checked pccasegear.com.au and put together a similar system using better quality parts and adding a video card in that I know will work for boxing. It's more expensive but you could save a little by going with the 2500k rather than 2600k or going down levels in videocards but if I were putting together a small system purely for boxing I don't think there is anything I would change in this setup apart from a Z68 mobo rather than the H61

BitFenix Survivor Core Black Gaming Case- $89
Intel Core i7 2600K - $315
Western Digital Green 2TB WD20EARX - $85
Corsair CMX8GX3M2A1333C9 8GB (2x4GB) DDR3 - $75
Samsung SH-222AB SATA DVDRW Drive - $25
ASRock H61M-VS Motherboard B3 - $59
Corsair CX-600 V2 Power Supply - $99
Sapphire Radeon HD6950 2GB Dirt3 Edition - $279
BitFenix Spectre 120mm Black Tinted White LED Fan x 3 - $28.50

Total - $1054.50

[EDIT]
If you remove the 6950 and add

Antec KUHLER H2O 620 CPU Cooler - $99
Gainward GeForce GTX 580 3GB Phantom - $609[/url]

you will be at $1483.50 but I'd ignore the Kuhler (unless you are looking at overclocking) and change the mobo to

Gigabyte GA-HA65M-UD3H-B3 Motherboard - $105

which is only $50 more than the ASRock and will allow you to expand to 16Gb in future if you wish
