Yeah a yellow top will help a lot! They're only about $80 to $100 too.
so a yellow top makes a difference? my lights dim noticeable at idle, i was going to throw in a 850cca yellow top and keep the stock alternator when i added my alpine 5 channel. do you think the extra amperage from optima alone will keep my lights from dimming? the stock battery is only 600cca, weak. i had a 1200cca bulldozer battery in my tundra, i could turn on 4 hellas, headlights, foglights and run my alpine headunit and amp with the engine off... when i turned the key the lights barely dimmed from the starter draw. that battery kicked ass :)

Yeah it should help out a lot. If not you can also get your alternator rebuilt too. You can usually get that done for about $20 to $40 around here.
cool, i'll get the yellow top and look into having the alternator rewound.
