I can't decide on two options: pls help

1. Amd 7750 BE + 770/780 chipset + 3870 + 2x2gb 800mhz cl5
2. Phenon II 710 + 790gx chipset |+ 4830 + 2.2gb 1066mhz cl5

Both have 2x samsung 500 gb 7200 rpm 16mb buffer in raid 0.

I use this computer for medium gaming, hard downloading ( and therefore multitasking ) and hd movies on a 32" lcd screen.

The second configuration in 33% more expensive. Do i get 33% more performance? Or is it better just to upgrade sooner from the first one?

My current config is 4000+, 2600Xt and 2gb 800 cl5 ram, so i think both will be a great upgrade.

Please let me know what do you think.

PS: I would like to try overclocking just for the fun of it ( but the 720 BE is more expensive ).

The second system all the way. 7750 is just an x2 6000+ in terms of performance. It will play all games, but in the difficult situations your fps will drop below 20. Phenom II has very smooth performance, (smoother than any CPU, even i7).

Thanks. But ofr me it's a matter of $/performance. Do i get 33% more performance? Anyway i'm not an enthusiast, but I want to play all the recent and future releases in gaming in a decent manner.

As I said it depends on the game and the situation. If you play an online first person shooter game with 20 players in the server shooting with their rockets, Phenom II may give you +150% performance, not only +33%. If you play Spore you will not see a difference.

In the difficult/demanding situations is where Phenom2 will show it's power. Benchmarks reviews never test those situations so it is up to you to decide.

I play only single-player games: Call of Duty, Crysis, etc fifa also with my 3 friends on my computer on 1280 x 1024 maximum resolutions . In addition 30 percent will be strategy games. However I'm looking forward to the new Total War, one of the most performance needer I know. Will the 7750 and the 3850 suffice?

The Phenom II system will probably grant more than 33% more performance. Processors are about the same frequency, but you have 50% more cores (2 -> 3), much more overclocking potential. The HD 4830 is leaps and bounds ahead of the HD 3870, and does an excellent job with AA enabled whereas the HD 3870 dies when you enable AA.

Would make more sense to get a 7750 and 4850 then oc as high as possible imo if you want $/performance, unless you plan to crossfire, then get a 4830 since they offer better performance in cf than 4850's in cf.

+1 for the system 2.
4830 is way faster than 3870 and you'll get an extra cpu core with better arch on a smaller process node. Should OC better as well...

Here's the thing, its smart to look toward the future, if your buying an amd your already on the right track, 4830 is a good choice also(even though i recommend a 4850 or ,i know this is a sin to amders but im only honest, a geforce 8800gt) good performance anyway you go.
I also recommend buying your amd chip in the black edition, although the regular chip provides excellent OCen, the black is a lot more edge for a tad more ching.
As with the phenom II, the sweet spot, from what i have seen in both benchmarks and real world apps, is around 4gig of 1066 memory, I like Kingston but i hear crucial rocks out great performance at a slightly higher budget. Remember, if your gonna be in a window xp environment, it will only use about 3.2,correct me if im to inaccurate, and they say, a 64-bit OS will only leave you with a 10% increase in realworld enviroment. And like an earlier poster said, you just cant benchmark realworld.
I am the owner of a Core 2 Duo Intel 8gig,1tb WD Green,8800gtx+. & an AMD Phenom II 720 x3 with 4gig 1066, 1tb wd green,and 8800gtx+.
I have to say, the benchmarks are close but the intel always hangs close or wins, in the benchmarks. But in use, I would gladly cut ties with the intel system due to its jerkiness in games, its ability to decide to lag when its in over its head, the amd always puts me(what I am seeing) first, it doesnt care whats going on in the background, it keeps my movements, in windows, or in games hands down, smooth as ice.

Noob here, i find all the stuff i know from trial and error,,, I didnt know the lateness of my comments, DUH!!. oh is me.

Thanks for letting me down soft dude. maybe I should do some studying and find out how things work in the forum.
